Exploring the 10 Most Popular and Widely Used Databases in 2024
Discover the top 10 most popular and widely used databases of 2024, their features, benefits and industry applications.

As we step into 2024, databases continue to be the cornerstone of modern information technology. They facilitate the storage, management, and retrieval of data across various industries. In this article, we explore the most popular types of databases dominating the technological landscape this year.
What is a Database?
A database is an organized collection of data, stored and accessed electronically within a computer system. Serving as a centralized repository for structured information, it facilitates streamlined data management and retrieval.
Definition of a Database
Essentially, a database comprises structured data sets electronically stored in computer systems. These systems are designed to efficiently manage, store and retrieve information. Data within databases is organized into tables with each table containing rows (records) and columns (fields). Each column represents a distinct data attribute while each row denotes a unique data instance.
Importance of Databases
Databases play a crucial role in modern business operations by enabling organizations to manage, store and access data efficiently. They ensure data integrity, security and accessibility across various applications. Businesses rely on databases for tasks ranging from customer relationship management and inventory tracking to financial transactions and analytics.
Moreover, databases facilitate efficient handling of large data volumes and rapid query responses. They support concurrent transaction processing, allowing multiple users to access and update data simultaneously without compromising consistency. Additionally, databases incorporate robust mechanisms for data backup, recovery and replication, essential for protecting against data loss and ensuring continuous operations.
Most Popular Databases in 2024
The following list of databases is based on Stack Overflow’s annual developer survey. SQL remains the undisputed leader. However, NoSQL databases are steadily growing in popularity. Their scalability and lower entry costs make them an attractive option, leading more companies to adopt these solutions.
Elasticsearch
lasticsearch is an open-source search and analytics engine built on Apache Lucene. It is a distributed, multitenant full-text search engine with an HTTP interface developed in Java, optimized for real-time searches and efficient results. Elasticsearch can handle various data types, including integers, floating-point numbers, strings, dates, geo-data, and more, in both structured and unstructured formats.
Despite its name, Elasticsearch functions as a comprehensive database for search, analysis, observability and security. Its open-source nature makes it an excellent choice for budget-conscious projects.
Firebase
Firebase Realtime Database is part of Google’s Firebase suite, offering a cloud-based document store with clients for iOS, Android, and JavaScript. Clients connect to a shared database. This ensures they always download the latest information.
Ideal for serverless projects, Firebase manages everything from the cloud. When a client is offline, the app caches data and uploads it once the connection is restored. This allows projects to scale without additional hardware investments. However, as Firebase operates under a commercial license, it is one of the more expensive options on this list.
Oracle
Oracle is one of the oldest databases on this list, with over 40 years in the market. It is a leading database for online transaction processing and data warehousing. Oracle offers a range of packages including on-site, on-cloud and hybrid options, tailored to different consumer needs. It supports all popular programming languages and a variety of data formats such as Relational, Columnar, XML, JSON, Spatial, Graph and unstructured data.
However, Oracle has two significant drawbacks: it is expensive and highly complex. Learning to use Oracle efficiently and maintaining a server can take considerable time. Despite these challenges, the benefits make it well worth the effort.
MariaDB
MariaDB, developed by the original creators of MySQL, is an open-source database designed to surpass its predecessor. It offers greater scalability, improved security, higher availability and enterprise-focused tools and services. The story behind MariaDB is quite intriguing. When Oracle acquired MySQL, some developers forked the project to ensure it remained open source.
MariaDB was developed as a drop-in replacement for MySQL. The command lines are nearly identical, making the switch from MySQL to MariaDB straightforward. You simply delete MySQL, install MariaDB and run a command line. Like MySQL, MariaDB supports all popular programming languages and can run on any server operating system.
Redis
The Remote Dictionary Server, known as Redis, is the most popular open-source key-value database on the market. Developed by Salvatore Sanfilippo to enhance his own projects, Redis has become essential for those seeking fast access and easy implementation.
What distinguishes Redis from other key-value databases is its persistence feature. It creates disk copies of data and retrieves them when needed. Common use cases for Redis include session caching, full-page caching, message queuing and leaderboards.
MongoDB
The creators of MongoDB describes it as the leading NoSQL solutio and its popularity supports this claim. MongoDB is the most widely used document-oriented database on the market. Its key advantage is being schema-less, which eliminates the need for upfront schema design and saves a significant amount of time. MongoDB is also known for its speed, boasting impressive benchmark results. It is relatively easy to scale compared to its competitors. Additionally, being an open-source solution contributes to its rapid rise in popularity.
SQLite
SQLite is the only RDBMS (Relational Database Management System) on this list that isn’t a client-server engine. Instead, it functions as a C library embedded directly in the end program. SQLite is perfect for situations where you need the full functionality of a relational database without the overhead of a server. For example, Firefox uses SQLite to store user information such as settings, history and bookmarks.
Developers building local applications involving data processing like financial analysis tools or data analysis software will find SQLite to be a powerful and efficient solution.
Microsoft SQL Server
Originally released in 1981, Microsoft SQL Server is one of the most popular and robust database services available. The extensive range of products under the Microsoft SQL umbrella might seem overwhelming at first, but, like Windows, the portfolio is designed for simplicity. There is a product for every client, making it just a matter of identifying the necessary functionalities. This is a case where less can be more.
Microsoft has always prioritized ease of use, resulting in one of the most streamlined installations on the market. Its cloud-based counterpart, Azure, is also one of the most advanced options for developers and businesses.Pos
PostgreSQL
Originally founded as Ingres, a database engine developed at the University of California, it eventually evolved into PostgreSQL. Since then, it has become one of the most well-known and well-supported open-source relational databases.
PostgreSQL is renowned for its transactions featuring ACID properties. It achieves this through innovative techniques like multi-version concurrency control. Furthermore, PostgreSQL benefits from having one of the most supportive and active communities in the IT world. For most developers, learning PostgreSQL is an obvious and valuable choice.
MySQL
It’s no surprise that MySQL takes the top spot on this list of popular databases. Created in 1995 and written in C++, MySQL is the gold standard for database engines. It supports nearly every system known. MySQL is well-known for its security, easy scalability and high performance. It has a strong community that continues to develop and update it. Currently owned by Oracle, MySQL is available under both open-source and proprietary licenses, catering to various needs.
Conclusion
In conclusion, the landscape of databases in 2024 is diverse and dynamic. It caters to the evolving needs of businesses across various industries. Ultimately, none of the popular databases discussed here is the definitive solution for all needs. Each has its own strengths and weaknesses, tailored to address specific problems. As time progresses and new trends emerge, we will likely see new approaches develop to meet the demands of evolving technologies.
