Top Most Popular Databases In The World 2025

The database landscape is still changing as of 2025, but some systems stand out for their scalability, robustness, and broad adoption. From small startups to multinational corporations, organizations depend on databases to effectively store, manage, and retrieve large amounts of data. As technology advances, cloud integration, and artificial intelligence (AI)-powered analytics become more common, databases have become even more sophisticated, meeting a variety of industry needs.

List Of Top Most Popular Databases In The World 2025

1. IBM Db2

An effective relational database management system (RDBMS) that is designed to manage massive amounts of structured and unstructured data, IBM Db2 is a sophisticated database management system. Transactional processing, analytics, and data warehousing are all areas that make extensive use of Db2, which was developed by IBM and is widely utilized in enterprise environments. Over the course of its existence, it has developed to accommodate the requirements of contemporary data management, which include cloud deployments, AI-driven optimizations, and hybrid data architectures.

2. Redis

Redis, which stands for “Remote Dictionary Server,” is an in-memory data structure store that supports high performance and is open-source. It may also be used as a database, cache, and message broker. Because of its reputation for speed, flexibility, and scalability, it is frequently selected for use in real-time applications, cache layers, and distributed systems. Redis was initially developed by Salvatore Sanfilippo in 2009, and since then, it has grown to become an essential component of modern web applications. It is capable of supporting a broad variety of use cases, ranging from session management to real-time analytics.

3. Elasticsearch

The distributed, RESTful search and analytics engine known as Elasticsearch was developed with the purpose of storing, searching, and analyzing massive amounts of data in real time. Full-text search, log analytics, business intelligence, and observability are just some of the applications that make extensive use of this platform, which is built on Apache Lucene. Elasticsearch is a component of the Elastic Stack (ELK), which was developed by Shay Banon in 2010. This stack also contains Kibana, which is used for visualization, Logstash, which is used for data processing, and Beats, which are lightweight data shippers.

4. Apache Cassandra

High availability, fault tolerance, and scalability are the three characteristics that define Apache Cassandra, which is a distributed NoSQL database that is open-source. The Internet of Things (IoT), artificial intelligence (AI), financial services, and cloud applications are all examples of applications that would benefit greatly from extensive data storage and real-time processing. Although it was initially developed at Facebook in 2008, Cassandra was officially adopted as a project by the Apache Software Foundation in 2010. Netflix, Twitter, Apple, eBay, Uber, and a great number of other businesses are among the many companies that use it today.

5. MariaDB

A robust relational database management system (RDBMS) that is open-source and designed to be a drop-in replacement for MySQL, MariaDB is a database management system. In 2009, the original developers of MySQL wanted to address concerns around the acquisition of MySQL by Oracle, thus they came up with this solution. The open-source commitment, performance, scalability, and security of MariaDB have earned it a reputation for excellence. Within the realms of enterprise software, cloud environments, and web applications, it is utilized extensively.

6. Oracle Database

Oracle Corporation is responsible for the development of Oracle Database, which is a relational database management system (RDBMS) that is considered to be of enterprise-grade. Because of its reputation for scalability, high availability, security, and advanced capabilities, it is the cloud platform of choice for large-scale applications, financial institutions, and workloads that are mission-critical. Oracle Database was initially made available to the public in 1979. Since then, it has developed into a multi-model database that supports SQL, NoSQL, JSON, Graph, and Blockchain. The cloud computing industry, big data analytics, and enterprise applications are all major users of this technology.

7. MySQL

Oracle Corporation is responsible for the development of MySQL, which is a relational database management system (RDBMS) that is open-source. The majority of web apps, enterprise systems, and cloud services are powered by this database, making it one of the most frequently used databases. Because of its reputation for speed, dependability, and user-friendliness, MySQL is a product that is frequently selected by enterprises, software developers, and new ventures. MySQL was first made available to the public in 1995, and since then, it has developed into a very effective database offering support for ACID transactions, high availability, replication, and cloud connectivity. It serves as the foundation for a wide variety of well-known web applications, including WordPress, Facebook, and Twitter.

8. Microsoft SQL Server

According to Microsoft, the relational database management system (RDBMS) known as Microsoft SQL Server (MSSQL) was developed by the company. Enterprise applications, data analytics, cloud computing, and workloads that are mission-critical are all common places where it is discovered and utilized. The SQL Server database management system is a popular option for companies of all kinds because of its high level of performance, security, and scalability. Since its initial release in 1989, SQL Server has developed to allow advanced analytics, processing of large amounts of data, and automation driven by artificial intelligence. Considering that it can be utilized in on-premise, cloud, and hybrid scenarios, it is among the most versatile databases that are now available on the market.

9. PostgreSQL

The sophisticated open-source relational database management system (RDBMS) known as PostgreSQL, which is also sometimes referred to as Postgres, is renowned for its extensibility, robust capabilities, and compliance with both SQL standards and industry standards. As a result of its scalability, performance, and dependability, it is utilized extensively in a variety of applications, including online applications, corporate systems, and big data solutions. PostgreSQL is a database management system that was initially developed in 1986 at the University of California, Berkeley. Since then, it has evolved into one of the most powerful databases, competing with proprietary approaches such as Oracle Database and Microsoft SQL Server.

10. MongoDB

MongoDB is a NoSQL database that was developed with the goals of providing high performance, scalability, and flexibility. Because it stores data as BSON documents, which are similar to JSON, MongoDB is an excellent option for modern applications that require dynamic and semi-structured data. Traditional relational databases, such as MySQL, PostgreSQL, and SQL Server, store data in a different format. MongoDB Inc. made it possible for it to become one of the most widely used databases for large data, real-time applications, Internet of Things development, and cloud-native development. It was developed in 2007.
