A database is just like a room in an office where all the files and important information can be stored related to a project. Every company needs a database to store and organize the information. The information that the company stores can be very sensitive so one has to always have be careful while accessing or manipulating the information in the database. Choosing the right database is completely dependent on the purpose of the project. In the year 2020, there are a lot of choices depending on your work and purpose.

Two major types of databases:

In the past, almost all databases were relational i.e. they used a set data structure, which allowed them to link information from different ‘tables’, using indexes. One of the biggest changes in database design came about in the 2000s, when NoSQL (No Structured Query Language) began popularizing the non-relational database.

  • SQL 

SQL databases define and manipulate data based structured query language (SQL). This language is extremely powerful. SQL is one of the most versatile and widely used options available which makes it a safe choice especially for vastly complex queries.

  • NoSQL

A NoSQL database has dynamic outline for unstructured data. Data is stored in many ways which means it can be document-oriented, column-oriented or graph-based. This flexibility means that documents can be created without having defined structure.

  1. Oracle


Oracle database is really popular among all developers. It is easy to use,  and amazing new features like JSON from SQL and so on. It’s a very powerful and secure database that has a well-written document. It takes less space and quickly processes data. Some of the other features are –

  • Oracle provides functionality for Cloud, Document Store, Key-value storage, Graph DBMS, PDF Storages, and Blogs.
  • It fulfills the requirements in the areas of performance, scalability, high availability, security and data warehousing.
  • It supports multiple Operating Systems such as Windows, UNIX, and various Linux versions.
  1. MySQL


MySQL is one of the most popular Open Source SQL database management systems. MySQL Database Software is a system that consists of a multithreaded SQL server that supports different back-ends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs).

  1. Microsoft SQL Server

Microsoft SQL Server

MS SQL Server is a relational database management system built for the basic function of storing and retrieving data as required by other applications.

  1. MongoDB


MongoDB is a cross-platform, document-oriented database that provides high performance, high availability, and easy scalability. It is based on the NoSQL document store model. The data objects are stored as separate documents inside a collection instead of storing the data into the columns and rows of a traditional database.

  1. Apache HBase

Apache HBase

HBase is an open-source, non-relational, distributed database modeled after Google’s Bigtable and is written in Java. It is developed as part of the Apache Software Foundation’s Apache Hadoop project and runs on top of HDFS (Hadoop Distributed File System), providing Bigtable-like capabilities for Hadoop.

  1. PostgreSQL


It is an open-source relational database management system developed by a worldwide team of volunteers.

  1. DB2


DB2 is a database product from IBM. DB2 is designed to store, analyze and retrieve the data efficiently.

  1. Redis


It is an open source, advanced key-value store and an apt solution for building high-performance, scalable web applications.

  1. Firebase


The Firebase is a real-time cloud-hosted database. Data is stored as JSON and synchronized in real time to every connected client. When one builds cross-platform apps with iOS, Android, and JavaScript SDKs, they share one real-time database instance and hence customers automatically receive updates with the newest data.

  1. SQLite


SQLite is a relational database management system contained in a C library. In contrast to many other database management systems, SQLite is not a client–server database engine. Rather, it is embedded into the end program. It is best for mobile application.

There are multiple popular databases, but each has its merits and disadvantages. However, what’s important is for you to pick the apt database best suited for your objectives and growth prospects.
