Irrespective of the organization, each organization requires a database to sort out and store its fundamental data. To provide such a facility, the database management system software is to the rescue.

A database can be referred to as a room inside an office where all the essential information and reports are stored. The information which gets stored is extremely sensitive, hence we have to be ultra-careful while we access the information in the database.

With the ascent of Microservices, Cloud, Distributed Apps, Semi-Structured Data, Big Data, Low Latency Data and so on, the customary SQL list of most popular databases are currently joined by different NoSQL, NewSQL, and Cloud databases.

Stating the wide use and popularity of different types of databases in responsive web development applications, here are some facts about the best database 2021 or upcoming years:

According to reports by, 91% of companies with more than 11 employees use CRM software.

A report by Nucleus Research states that 65% companies that are using mobile web development CRM are achieving their sales quotas.

Which Database Is Best In 2021?

1. The Oracle

Oracle is the most widely used commercial relational database management system, built-in assembly languages such as C, C++, and Java. This database’s most recent version, 21c, contains a slew of new features. 

Oracle is the database management system that stands above the others. Overall, it is the most extensively used RDBMS. It takes up less space and processes data faster, and it includes several new useful features such as JSON from SQL.

2. MySQL

MySQL is one of the most popular databases to use in 2021 in the computer world, especially in  web application development. The main focus of this database is on stability, robustness, and maturity. The most popular application of this database is for web development solutions

MySQL is written in C and C++ and uses a structured query language. MySQL 8.0 is the most recent version of this database, and it includes a better recovery option. The best SQL database comes in a variety of editions, each with its own set of features.

3.  MS SQL Server

Microsoft provides great toolset support for one of this best database software, both on-premise and in the cloud. It’s attuned well with Linux and Windows systems. MS SQL is a multi-model database that supports Structured Data (SQL), Semi-Structured Data(JSON), and Spatial Data.

It is not as inventive or advanced as other modern list of popular databases, but it has undergone considerable improvements and overhauls over the years.

4.  PostgreSQL

POSTGRES was the initial name of the database. Michael was also honored with the Turing Award for his contributions to PostgreSQL.

5.  MongoDB

When it comes to most popular databases to use in 2021 through a NoSQL database, there are a few things to consider. MongoDB is the first Document Database management software that was released in 2009. It is challenging to load and access data into RDBMS using object-oriented programming languages which also require additional application-level mapping. Thus, to overcome this problem, Mongo was developed to handle Document Data.

6.  IBM DB2

IBM also offered DB2 LUW for Windows, Linux, and Unix. DB2 11.5 is the most recent release, and it speeds up query execution.

The list of databases for mobile apps supports the relational model, but it has grown significantly in recent years. It now supports object-relational features and non-relational forms such as JSON and XML.

8.  Elasticsearch

Elasticsearch is an open core full-text search engine based on Lucene that was first released in 2010 by Shay Banon. It’s a full-text search engine with a distributed, multi-tenant capability and a REST API.

It provides horizontal scaling via automatic sharing and REST API. It also supports structured and schema less data (JSON), which is especially suited to analyze Logging or Monitoring data.

9.  Cassandra

It is an open core, distributed, wide column store and commonly used database for an application that was developed in 2008. This is a highly scalable database management software that is widely used by the industries to handle massive data.

One of its main features is its decentralized database (Leaderless) having automatic replication and multi-data center replication, leading it to become a fault-tolerant base without any failures. Cassandra has several different operations and infrastructure. Cassandra and HBase databases go a long way and have different use cases according to their types.

10. MariaDB

It is a Relational Database Management System which is compatible with MySQL Protocol and Clients. The MySQL server can be easily replaced with MariaDB without requiring any code changes.

This management system provides columnar storage with massively parallel distributed data architecture. In comparison to MySQL, MariaDB is more community-driven.


11.  OrientDB

OrientDB is an open-source database with NoSQL multi-model database program that enables businesses to leverage the capabilities of graph database management software without having to build several systems to handle different data types.

It is a management solution with support for graph, document, key value and object-oriented database models that improves performance and security while also allowing for scalability.

What Is The Easiest Database To Use?

Database software tools power pretty much every application you can consider. But here, the query is truly for which purpose you’re looking for. For example, at university, we train novice students about list of databases in web applications and software using Microsoft SQL Server. When they ace the database essentials, they can without much of a stretch progress to MySQL and Oracle.

While most databases for mobile apps are the same, it is fundamental to become familiar with the basics of most popular SQL databases and explanations since they can be applied easily to most and popular database systems. It would be better for you to learn it by composing SQL statements first as opposed to utilizing a GUI approach.

When you understand the key ideas, you’ll see that it’s such a simple way to apply them to any database management software utilizing any IDEs, GUI included.

Which Database Is Best For Python?

The Python programming language has amazing database programming features. Python upholds different list of databases like SQLite, Oracle, MySQL, PostgreSQL, and so forth.
