But, how do you think, we can handle data present in various formats and generate useful insights. Well, to do that, we need the database management systems(DBMS). In this article, I will explain to you what is DBMS in the following sequence:What is Database?Introduction to DBMSCharacteristics of DBMSTypes of DBMSAdvantages and Disadvantages of DBMSBefore we understand about DBMS, let us understand what is a database and how it plays an important role in database management systems.What is a Database?As the name suggests, a database is a place where all the data gets stored in a structured format. It helps the users to easily access, manage and update the required information. So, in layman terms you can understand, a database as a big container wherein all the information about a website, or an application is stored in a structured format.For example, a company can have various detai ls of employees, such as name, empID, email, blood group, salary, and so on. All these details can be stored in a database with the name Employee in a structured format such as tables, hierarchy, etc.In any organization, be it a startup or a hyper-growth company, many databases can be present, but it is very important to manage those databases in a proper manner. So, next in this article let us understand how to manage these databases.What is DBMS?DBMS or Database Management System is a software application used to access, create, and manage databases. With the help of DBMS, you can easily create, retrieve and update data in databases. A DBMS consists of a group of commands to manipulate the database and acts as an interface between the end-users and the database. Refer below.Database Management Systems also aims to facilitate an overview of the databases, by providing a variety of administrative operations such as tuning, performance monitoring, and backup recovery.Database Managem ent Systems allows users to do the following:Define Data Allows the users to create, modify and delete the definitions which define the organization of the database.Update Data Provides access to the users to insert, modify and delete data from the database.Retrieve Data Allows the users to retrieve data from the database based on the requirement.Administration of users Registers the users and monitors their action, enforces data security, maintains data integrity, monitors performance and deals with concurrency control.Characteristics of DBMSThe following are a few characteristics of DBMS:To limit the permissions of the usersProvide multiple views of the single database schemaFacilitates security and removes data redundancyAllows multi-user transaction processing and sharing of dataFollows the ACID propertyOffers both physical and logical data independenceNow, let us move forward and understand the types of DBMS.Types of DBMSFollowing are the different types of DBMS:Hierarchica l DBMS: This type of database management system showcases a style of predecessor-successor type of relationship. You can consider it to be similar to a tree, where the nodes of the tree represent records and the branches of the tree represent fields.Relational DBMS (RDBMS): This type of Database management system, has a structure which allows the users to identify and access data in relation to another piece of data in the database. In this type of DBMS, the data is stored in the form of tables.Network DBMS:This type of database management system supports many to many relations where multiple user records can be linked.Object-orientedDBMS:This type of database management system uses small individual software called objects. Here, each object contains a piece of data and the instructions for the actions to be done with the data.Some of the popular DBMS software are MySQL, PostgreSQL, Oracle, SQLite, MariaDB, MS SQL Server, etc. All these software are based on different types of DBMS available in the market. So, it is completely the users choice, on which type of database will suit his/ her data, and prove beneficial to generate meaningful insights.Moving forward in this article, let us look into the advantages and disadvantages of DBMS.Advantages and Disadvantages of DBMSAdvantages of DBMSFew of the advantages of the database management system are as follows:It offers a variety of methods to store and retrieve various formats of data using the query language.It can be easily maintained because of its nature of a centralized database system.Facilitates multiple applications using the same data with less development and maintenance time.Provides data security and integrity with minimal data duplicity and redundancy.It allows seamless integration into the application programming languages like Java and Python to enable the users to connect a database with any application or website.Has automatic backup and recovery systems to create an automatic backup of data.Aut horizes users who can view, share and access data.Disadvantages of DBMSDatabases Management Systems are often complex systems.Few of the DBMS available in the market are licensed. So, you have to pay to us that DBMS in your organization.Most leading companies store their data in a single database. Hence, if that database is damaged due to any reason, the complete data would be lost.DBMS that you wish to use might not be compatible with an organizations operational requirements.DBMS are large in size and need time to setup.Well folks, with that we come to an end to this article on DBMS. I hope you found this article informative.
