PaaS is a Subscription model for utilizing framework administrations. Present day foundation abilities bolster cloud engineering. This administration gives simple arrangement and savvy maintenance e.g.:- Database cloud benefit, Java cloud benefit (PaaS information management, security, and incorporation). Stage as-a-benefit (PaaS) is a kind of distributed computing offer in which a specialist organization conveys a stage to customers, empowering them to create, run, and oversee business applications without the need to construct and keep up the framework such programming improvement forms usually require.

How can it function?                                                                

PaaS does not commonly supplant a business’ whole IT framework. Instead, a company depends on PaaS suppliers for critical administrations, for example, application facilitating or Java advancement. Clients can center on making and running applications as opposed to developing and keeping up the fundamental foundation and administrations.

Points of interest of PaaS

The upsides of PaaS are principal that it takes into consideration more considerable amount programming with drastically decreased multifaceted nature; the general advancement of the application can be more successful, as it has inherent/self all over sloping foundation assets; and support and upgrade of the application are in this way less demanding.

PaaS’s business advantages and drivers

One of the greatest preferences of PaaS is that ventures can pick up a situation in which they can make and send new applications without the need to invest energy and cash fabricating and keeping up a foundation that incorporates servers and databases. This can prompt speedier advancement and conveyance of utilization, a tremendous in addition to for organizations hoping to pick up an aggressive edge or that need to motivate items to showcase rapidly.

PaaS advances and suppliers

PaaS incorporates numerous hidden cloud framework parts, including servers, organizing hardware, working frameworks, stockpiling, middleware, and databases. These are possessed and operated by the specialist organization.

PaaS likewise incorporates assets, for example, advancement apparatuses, programming dialects, libraries, database administration frameworks and different devices from the supplier.

Among the foremost PaaS, merchants are Amazon Web Services, Microsoft, Google, IBM,, Red Hat, Mendix, and Heroku. Most generally utilized dialects, libraries, compartments, and related apparatuses are accessible on all the major PaaS suppliers’ mists.

Significant dangers while utilizing PaaS

PaaS is a cloud-based administration; it accompanies a large number of the same inalienable dangers that other cloud contributions have, for example, data security dangers. PaaS depends on the idea of utilizing shared assets, for example, systems and servers, so the security dangers incorporate putting necessary information into this condition and having the data stolen because of unapproved access or assaults by programmers or other awful performing artists

Additionally, because associations are depending on a specific specialist co-op’s framework and programming, there is a potential issue of seller locking with PaaS situations.

Another hazard with PaaS is the point at which the specialist co-op’s foundation encounters downtime for reasons unknown, and the effect that may have on administrations. Likewise, imagine a scenario where the supplier rolls out improvements in its advancement system, programming dialects, or in different areas? Nevertheless it gives greater adaptability correctly because the merchant handles the stages while you feel the programming.


The other option to PaaS is to create web applications utilizing work area improvement instruments like Eclipse or Microsoft Access, at that point physically send those applications to a cloud facilitating supplier, for example, Amazon EC2.

PaaS stages likewise have useful contrasts from general advancement stages. These include:

  • Multi-occupant improvement instrument: Traditional advancement devices are single client – a cloud-based studio must help different clients, each with various dynamic tasks.
  • Multi-occupant organization engineering: Scalability is frequently not a worry of the underlying improvement exertion and is left instead for the sys administrators to manage when the undertaking sends. In PaaS, adaptability of the application and information levels must be implicit (e.g., load adjusting; failover should be essential components of the stage itself).
  • Integrated administration: Traditional improvement arrangement more often than don’t fret about runtime checking, yet in PaaS, the observing capacity should be heated into the advanced stage.
  • Integrated charging: PaaS contributions require components for charging given utilization that is extraordinary to the SaaS world.

Significant illustrations:

Some real Examples incorporate Salesforce Heroku, AWS Elastic Beanstalk, Microsoft Azure, and Agile Scrum.


In this era of modernization, the world has entered into the 4th Industrial Revolution; everyone has two simple choices: lead or perish. The problem is that the cognitive transformation is sweeping through the global economy, and it is not like anything traditional leaders have ever experienced before.

As financial services, healthcare and auto sectors are discovering more, the emergence of intelligent automation is remaking the competition rules in the entire world. Through, this change, the idea of leadership is getting innovations. The adverse impact of it is that if the leaders have fewer capabilities of understanding and learning their career will leave behind in the race. The robotic automation would prove fatal for some companies or industries if they do not adopt it.

What is RPA?

Robotic process automation (RPA) is the use of software with artificial intelligence and machine learning capabilities to handle high-volume tasks that previously required humans. These tasks can include queries, calculations, maintenance of records and transactions. RPA technology, sometimes called a software robot mimics a human worker, logging into applications, entering data, calculating, completing tasks, and logging out.

The evolution of RPA

Although the term “robotic process automation” can be traced back to the early 20th century, it had emerged for some years previously. RPA evolved from three key technologies namely: screen scraping, workflow automation, and artificial intelligence.

A possible Threat to humans

The development of robotics combined with computers poses a problem even more critical than the loss of jobs. A new system is evolving, transforming the work environment but with ramifications beyond the workplace. The introduction of robots need not consider humans as essential elements in the order. Modification in the human environment thus raises the question of human adaptability and also the nature of the man-machine relationship and also whether humans are more trustworthy or robotic systems.

Advantages of Robotic Process Automation

The software robots used in robotic process automation are programmed to do the tasks in a particular workflow by the employees with some assistance from programmers. RPA is a more straightforward product than an artificial intelligence-driven system or enterprise driven system that brings all the data in one spot. Which makes it a cheaper product that IA or enterprise.

Paybacks of RPA

Robotic process automation technology can help organizations in:

  • Having improved benefits.
  • Ensuring business tasks and procedures consent to directions and norms.
  • Allowing procedures to be finished significantly more quickly.
  • Providing enhanced effectiveness by digitizing and inspecting process information.
  • Creating cost funds for manual and dreary errands.
  • Enabling workers to be more successful.

Uses of RPA

A portion of the best uses of RPA include:

Client benefit: RPA can enable organizations to offer better client benefit via mechanizing contact focus undertakings, including checking e-marks, transferring examined reports and confirming data for programmed endorsements or dismissals.

Bookkeeping:  Organizations can utilize RPA for general accounting, operational auditing, value-based revealing, and planning.

Budgetary administrations: Companies in the money related administrations industry can utilize RPA for remote trade installments, mechanizing account openings and closings, overseeing review demands and preparing protection claims.

Human services: Medical associations can utilize RPA for dealing with understanding records, claims, client bolster, account administration, charging, detailing an investigation.

HR: RPA can computerize HR assignments, including onboarding and offboarding, plus Microsoft Courses On-Demand.

What to search for in RPA programming

At the point when endeavor pioneers search for RPA advancements, they ought to think about various things, including:

  • Scalability: Organizations shouldn’t choose RPA programming that expects them to convey programming robots to work areas or virtualized conditions. They should search for RPA stages that can halfway oversee and scale hugely.
  • Rapidity: Enterprises ought to have the capacity to outline and test new mechanical procedures in a couple of hours or less, and also streamline the bots to work rapidly.
  • Reliability: As organizations dispatch robots to computerize hundreds or even a considerable number of undertakings, they should search for apparatuses with worked in observing and investigation that empower them to screen the soundness of their frameworks.
  • Intelligence: The best RPA instruments can bolster straightforward errand based exercises, read and keep in touch with any information source, and exploit further developed figuring out how to enhance computerization additionally.
  • Enterprise-class: Companies should search for instruments that produced starting from the earliest stage venture review adaptability, consistent quality, and reasonability.

Data Warehousing

Just as the name suggests, Data warehousing defined as “a subject-situated, incorporated, time-variation and non-unpredictable gathering of information in the help of the administration’s basic leadership process.” The server farm, as we have come to know it, is the focal area that houses the assets and offices for dealing with every one of the information utilized by an association’s applications. Not very far in the past, a few sellers needed to begin calling this place the information stockroom, envisioning a market where organizations accumulate business insight information for quite a long time. Then, incorporate that information away volumes of regularly expanding limit yet consistently contracting physical size, and associations transfigure themselves into massive protected innovation files, the focal point of endless amounts of certainties and archives.

What is Data warehousing today?

The process of today’s version of data warehousing (DW) is much less centralized, much more dynamic and it still involves the process of collecting and storing business intelligence data. However, it is no longer a massive database. Because of the development of cloud innovation, an information distribution center is never again only one thing with one brand. It’s not in any case only one place, except if you tally “Earth” as a place. It can be the result of numerous brands and numerous segments cooperating.

How does the warehouse function?

A data warehouse has data suppliers who are responsible for delivering data to the ultimate end users of the warehouse, such as analysts, operation personnel, and managers. The data suppliers make data available to end users either through SQL queries or custom-built decision support applications. (e.g., DSS and EIS)

Components of the Modern Data Warehouse

The modern data warehouse is to varying degrees depending on the organization, comprises the following elements.

  1. A typical, organized information distribution center, made up of composed records in segments or tables, ordered and intended to be recovered by databases. I know it sounds repetitive to state a distribution center comprised of a stockroom. However, we don’t generally have a term yet for the “meta-stockroom” that consolidates these things.
  2. An unstructured information store, which is regularly dealt with nowadays by a “major information” motor toward the back called (for the absence of any extra words in the English Dictionary) Hadoop. With this new open source working framework only for information, worked on the HDFS document framework, information that presently can’t seem to be parsed or even taken a gander at can gathered in a pool that traverses numerous volumes more than one stockpiling gadget or capacity organize.
  3. Cloud-based capability, which contained space rented from administrations like Amazon and Rackspace. While distributed storage conveys with it a conspicuous cost, it might indeed be more affordable for organizations to rent distributed storage off-start than to keep up an information stockroom on-preface – which for the most part requires a full-time IT authority.
  4. Data streams, which are caches of data collected from specific sources, with the intention of being kept only for a limited time. Some BA tools may look at temporary data, such as the flow rates of petroleum through pipelines, and render analytics based on that data. The analytics may be kept indefinitely, whereas the data may discard at some point.

The amalgam of these vastly different sources, all of which have separate modes of access and maintenance, is what BI vendors and experts refer to today as Scaled Agile, better known as SAFe.

The evident risks behind the startup of Data Warehousing

Although Data warehousing is a product of business needs and technological advancement, and on the other hand customer relationship management and e-commerce initiatives are creating requirements for large, integrated data and advanced analytical capabilities. For this, they require a warehouse. However, the risk behind a warehouse is enormous as the warehousing project is costly. Additionally,  estimated that during the startup, one-half to two-thirds of data warehousing efforts fail. The most common reasons for this failure include weak sponsorship and management support, insufficient funding, inadequate user involvement, and organizational politics.

The key factors involved in Data warehousing success

The following factors commonly heard but play a crucial role in the success of Data warehousing.

  • Management Support
  • Resources
  • User participation
  • Team skills
  • Upgraded source systems
  • Organizational implementation success
  • Project implementation success
  • Data quality
  • System quality
  • Perceived net benefits

Microsoft Remote Desktop Services


Remote Desktop Services:

Remote desktop services provide you with an opportunity to be in two places at one time virtually. The service allows you the access of all the programs on the remote machine through the machine that you are using physically provided that both the stated devices be connected through the internet and have the program supporting Microsoft Remote Desktop Services installed.

With Microsoft:

The software comes in a pair where the machine to be accessed, that is the server (terminal server) must have the host version of the software while the client that is the users that will access the terminal server must have the client version installed. The terminal server has control over the type of access that each client gets. It can either restrict the access entirely making sure that the client can only view the server and make no changes to it or it can provide the complete access or something in between. The term terminal server has used since the first Microsoft Remote Desktop Services. The server is capable of delivering more than one connection that are more than one clients can access at a time depending on the software that used since the older versions don’t support many links at a time.


The software is highly compatible. It can be used even on devices which have either Macintosh or UNIX installed and through this software you can have a Windows experience while using these devices. This means that not only it allows connecting to remote systems, but it also provides for the connection between different operating systems.


The components of the Remote Desktop Services include:

  • Connection Broker: This is the main component in establishing a link between the client and the host. This is also an essential node regarding the disruption of a connection between the two parties. In that case, the broker makes it possible that the relationship restored without the loss of the session that is in progress.
  • Gateway: This is the bridge that forms a connection between the host and the program supporting these services on a client system.
  • Licensing: This is an integral part of the software since without license the usage is named under the illegal and the functionality of the program cannot adequately utilize. It keeps a record of the usage of the license that comes with the original software.
  • Session Host: This is an integral component of the host system that allows the server to organize a session which will enable the clients to interact with the host machine.
  • Virtualization Host: This lets the process of Digital Strategy and Transformation to take place.
  • Web Access: This is the component which allows the client to access the server machine either through the use of some web browser or by their Start Menus.

Since simplicity is what drives the user to get a program the Windows Remote Desktop Services to focus on it and is thus a popular choice.


User environment management

An Introduction:

A personalized desktop with the Operating System working exactly as you want it to be is a dream of every user. Operating System designers collect information to see which feature that attracts the user and then incorporate such more features to have better user feedback. The new way to achieve this is through user environment management also known as UEM. UEM is all about the exclusive rights the IT gets to look at the desktop of the user including details like the profile of the user and the personalization the user does. The IT administrator is in control of the entire settings of the desktops, and different users will provide a different output. To achieve this copy of the parameters made in a central location where the information and the settings are stored concerning each user and stored to separate profiles. This is the complete report on the interactions of the user so that the IT knows which areas to focus and make the experience even better for the user by making the desktop further adaptable to the user preferences.

The managing:

The management made more accessible for the IT professional since there is a GUI (Graphic User Interface) available which used in controlling the permissions for more than one level. This is used to keep in check that a user in a group doesn’t overuse a shared device to the point where the resource is exhausted and becomes unavailable to use by the other users in the same group. In the case where this is in progress, the IT holds the right to disable the user from accessing that specific peripheral. The time of login and the period of the login is also noted so to keep a record of which user needs which customization and what needs to take away from the user.

The evolution:

The necessary tools that have used for the management are folder redirection and the use of Group Policy. With the group policies, the situation can become a bit chaotic in the case the administrator rights are restricted this will restrict the user from using the applications too and as soon as the number of users in the group increases it becomes even more challenging to manage it to perfection.

The next came the concept of roaming profiles where the information for each user saved in a central system rather than storing it on hard drives. This also has become complicated due to the increase in organizations and the more the users grow the manipulation and storage has become even more difficult.

These standard utilities replaced by full proof third-party software which dedicated to the purpose of the user environment management. The first such software appeared in 2007, and from then the updates is being made to make the procedure even better with better results so that the user experience can be enhanced further.


A technology designed to allow IT to see complete desktop experience, any policies IT applies, including Enterprise Architecture and the customization of user makes.

IaaS (Infrastructure s a Service)

The cloud-based computing is a significant term which contains a lot of different things starting from servers and infrastructure to office software, a lot of IT sold on a cloud-based service model. This initially means that any comparison between cloud providers can not only be very complicated but can also end up measuring companies that don’t even compete with each other. Moreover, to avoid this situation, different types of cloud services should be looked at separately. Currently, we are going to focus on infrastructure-as-a-service (IaaS).

IaaS is a subscription model for using hardware (infrastructure) related services. IaaS allows hardware engineers to use a hardware subscription for development and maintenance with a few clicks only.e.g:- Oracle’s storage cloud service, Compute cloud service, and Network Cloud service. Other resources like virtual-machine disk image library, block, and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks, etc. might also include.

Types of IaaS Cloud offerings

Presently, there are three sorts of IaaS Cloud contributions:

Open IaaS Cloud: In the general population cloud, provider(s) lease equipment assets in a multi-inhabitant strategy to the overall population utilizing virtual innovation. This enables numerous clients to share server assets. People in general cloud is a prime case of the distributed computing model which is difficult to set up, exceptionally adjustable and malleable, where customers pay for their assets.

Private IaaS Cloud: The private cloud utilizes virtualization innovation and conveys distributed computing administrations to a single association. The management provisioned secretly and sit behind the firewalls oversaw by the individual business. Servers and belongings are particularly committed to the particular market, and can’t utilize by others. The private cloud is most appropriate for organizations that have substantial CAPEX spending plans and depend without anyone else server farm experts and security specialists, who are expected to give more control over the registering environment(s).

Half and half IaaS Cloud: A cross breed cloud is by, and widely considered the blend of physical and virtual foundation in an open or private cloud. For instance, an organization may pick to deal with some physical servers in a private cloud, while outsourcing different servers to a public cloud. The half and half cloud enable organizations to exploit versatility with cloud advancements while overseeing touchy organization information or applications not reasonable or licensable in the cloud.

Important aspects of cloud computing

Pricing Plan – Providers offer pay-as-you-go (usually hourly) plans, monthly pricing plans, “membership” discounts (where the user receives a cut in usage rates in exchange for an extra yearly payment), or any combination thereof. The more options provided, the better it would be.

Service Level Agreement (SLA) – The uptime SLA offered (regardless of past performance), in percentage points.

Scale Up – If it is conceivable to scale up single cloud server examples by including more memory, additional CPUs or more storage room.

ScaleOut – If it is conceivable to convey new server cases rapidly.

Certifications – If the vendor has compliance- and security-related certifications, such as PCI or SAS 70.

Number of Datacenters – The number of data centers offered as a choice when deploying cloud servers.

Support – A three-level subjective scale (Poor, Average, extensive)

Monitoring – Another three-level subjective scale (Poor, Average, extensive)

 APIs – If the organization offers APIs to cooperate with the servers or not.

Complementary plan – If the supplier has a “free preliminary” level that clients can use to test the service. So organizations ought to be judged entirely on this criteria keeping in mind the end goal to show signs of improvement information about the best specialist co-ops.




Iaas providers

IaaS provider companies offer a range of of things from networking to storage on a usage-based payment model. They typically make substantial investments in data centers and other infrastructure, and then rent it out, allowing consumers to avoid investments of their own.

Some of the best examples of IaaS providers are:-

  • Amazon AWS.
  • Digital Ocean.
  • Microsoft Azure.
  • Rackspace Open Cloud.
  • Google Compute Engine.
  • HP Enterprise Converged Infrastructure.
  • IBM SmartCloud Enterprise.
  • Green Cloud Technologies

Why White Hat SEO Will Beat Out Black Hat SEO

SEO stands for search engine optimization, and the primary purpose of SEO is to increase the quality and quantity of traffic to your website. The importance of search engine defines that it improves the user experience of a site. There are three types of SEO which include white hat SEO, black hat SEO, and Grey hat SEO. Firstly we need to discuss what white hat SEO is and how it works for a website. If you want to get most relevant and trustworthy results from the search engine, then you have to update and upgrade the algorithms.

SEO Types

The two main SEO types are Black Hat SEO and White Hat SEO. These are the SEO techniques which help you to get the unique status of SEO, but these two methods follow different ways. Firstly we need to define what white hat SEO is. It is an SEO technique which follows the rule of a search engine in a positive way to get better results. This method supported by high-quality content, manual outreach, and research. If you are using this technique, then you can expect a long lasting growth of your site in ranking.

Black Hat SEO is another type of SEO technique, but it is opposite to the white hat SEO. The level of this method is low because of keyword stuffing, hidden link, and hidden text. If you are using this technique, then you should keep in mind that it gives short lasting growth in rankings. The term black hat is used to tell about computer hackers and people doing unethical actions. Most of the people use white hat SEO because it has long-lasting growth in rankings. Blackhat SEO techniques are those techniques which search engine do not like, and these procedures apply aggressive SEO strategies. After discussing SEO techniques here, the question is Why White Hat SEO Will Beat out Black Hat SEO

We have two ways of doing things, the honest way and the wrong way. Like this white hat and black hat SEO are the two ways to reach the goals. Here are some of the white hat SEO techniques to double the traffic of your site. Firstly you should plan for unique content to get more traffic. If you are using exclusive content, then it can increase the traffic and engage more users. Link building is another and the remarkable way of getting more traffic. In white hat technique, you can contact the domain owner for requesting a link from their sites.

Difference between them

The central and vital difference in black and white hat SEO is that white hat SEO is actual marketers. The primary goal of white hat SEO is to understand the needs of a target audience. The result of this technique is long lasting as compared to black hat SEO. White hat SEO beats black hat SEO technique because of the conduction of keyword research. There are some of the reasons not to use black hat SEO. These ideas include cloaking. It is a practice of deceiving the search engine by showing different content to Google for your site ranking. Exchanging links can also reduce the ranking of your website. You can get many links in lesser time, but this thing will not help you to improve your website rankings. Using duplicate content is one of the worst black Hat SEO techniques. If you are using duplicate content on your site, then it is considered as plagiarized content or data. Therefore you need to focus on your SEO efforts in creating unique and original website content.

There are many blog sites which use spam methods to publish their post. It also included in black hat SEO technique. Google Panda Update can detect the spam content and remove them from ranking list. You have to write relevant and useful content which attracts more users and target audience. These are some of the reasons why white hat SEO will beat out black hat SEO. There is a risk in using black Hat SEO because this technique will not rank your post for a long time. So the method mentioned above is used by those who want to gain quick results.

For better performance of SEM, SEO can be paired with Google Adwords for a dramatic difference. The expertise in using Google Adwords is essential for marketing campaigns and it is possible to master it with sufficient training.

Development of Internet

Today we cannot imagine our work without using the internet. The Internet has transformed the computer world and communication would like nothing before. If we talk about the inventor of the web, then the internet has no single inventor. It has evolved. The Internet is specially used to communicate and share data with one another, but today we can use internet for almost everything. We can say today we cannot imagine our life without internet. The initial concept of the internet originated in many computer science labs in the United States. The Internet is the invention of many scientists, programmers, and engineers who developed many new technologies and features. The Internet is a vast network, and it has a medium of collaboration and interaction between different computers.

There is an immediate increase in the number of computers connected to the internet, and it also increases the number of computer internet users. Today almost one-third of the world’s 6.9 billion people use the internet regularly. In 1957, Soviet Union launched the first human-made satellite. That satellite as known as Sputnik. The idea of the internet given before the Cold War. After the Sputnik’s launch, Americans think seriously about new technologies.

The Birth of the ARPANET

After the meeting of scientists and many military experts, they proposed the solution of the problem a galactic network” of computers that can talk to one another. In 1965, a scientist developed the way of sending information from one computer to another which he named packet switching. We can define packet switching as the break down of data into packets and block before sending the data to its destination. In 1971, the scientist Ray Tomlinson sent the first email by himself over the same network using different machines. The first shooter game developed in 1974. Then, Telenet launched, and it provides new pay-for-access internet available to the public.

The World Wide Web

In 1980, many scientists and researchers sent files and data from one computer to another. In 1991, the concept of the internet changed again. Many computer programmers introduced World Wide Web. World Wide Web define an internet that not only send information from one place to another, but it also transfers web information anywhere. Berner-Lee developed the internet that we have associated today. After some years, Web used for commercial purposes, and after this, many companies used to start internet to start their business and sell goods directly to customers. Today, the most popular way to stay connected with the world is social networking websites like Facebook, Instagram. A new communication protocol established in 1983 called Transfer Control Protocol or Internetwork Protocol. This protocol allows different computers to talk to each other. Universal language can connect all the networks. There are various networks in computer internet. The earliest computers were connected directly to the terminals. Typically, in the same building. Wide Area Network is a type of systems in which different computers are connected far apart from having a radius of more than 1 or 2 km.

Master Internetwork solutions with Cisco courses and you can excel at network design easily.

Database Management

Database Management System is software which used for creating and managing databases. Firstly we need to know why it is essential to maintain your information. Managing information means to align and link it actively. This management system provides the users and programmers a best systematic way to create, retrieve, update and manipulate the data. Database management has become a necessary part of business data. Due to the fast growth of data, there comes a variety of adverse conditions which includes poor application performance and compliance risk. A database management system manipulates the data itself, the data format, field names, record structure and the file structure. It also defines the critical rules validate and manage the data. The interaction with the database is possible with fourth generation query languages such as SQL.

Database management consists of three elements.

  1. Physical Database: it is the collection of files that contain the actual data.
  2. Database Engine: it is a software that modifies the contents of the database.
  3. Database Scheme: it is the specification of the logical structure of data stored in the database.

Components of DBMS

There are five critical components id DBMS which lays significant role.

  • Hardware
  • Software
  • Data
  • Users
  • Procedures

Functions of Database Management System

The primary purpose of database management is to organize the files to give you more control over your data. It provides you best backup and recovery function. You can easily backup your data regularly and recover the information if any of the problems occur. The structure of database improves the integrity of data. There is a data dictionary that describes the data. Database administrators also control the access and security aspects. Multiuser access control is an important and the most useful tool in DBMS. It enables the multiple users to access data without affecting the integrity of the database.

DBMS is most important because it is useful for providing a centralized view of data that can be accessed by multiple users from multiple locations. Database management system can offer you both logical and physical data independence. It also includes the function, and it also serves as an intermediary between user and database. The database is the collection of files so you can easily access the data in those files through DBMS.

Types of DBMS

Database Management System categorized according to their data structure or types.

  1. Relational Database Management System
  2. In-memory Database Management System
  3. Cloud-based Database Management System
  4. Flat Database Management System
  5. Object-Oriented Database
  6. Hierarchical Database System

When a database management system used, the system can be modified easily when the requirements of business change. If you want to add new categories of data, then you can quickly add it with the help of database management without disrupting the existing system and the application can be insulated from how data is structured and stored. Database management performs many objectives which include performance, storage optimization, efficiency, security, and privacy.
