Choosing the Right Database: Insights into the Most Popular Databases for Developers in 2020

In the rapidly evolving world of software development, databases play a crucial role in managing data efficiently. Developers rely on databases to store, retrieve, and manipulate data seamlessly. However, with numerous databases available, choosing the right one can be a daunting task. In this article, we will explore the top 10 most used databases by developers in 2020 and understand why they have gained popularity.


Developers have diverse requirements when it comes to databases. Some prioritize performance, while others focus on scalability or ease of use. Understanding the most popular databases provides valuable insights into the industry’s trends and preferences. Let’s dive into the top 10 databases that garnered significant attention from developers in 2020.

Importance of Databases for Developers

Databases are the backbone of modern applications, enabling developers to organize and manage data effectively. They offer a structured approach to data storage, allowing developers to query and retrieve information effortlessly. Databases provide reliability, security, and integrity to applications, ensuring data consistency and availability. Choosing the right database is crucial as it impacts the application’s performance, scalability, and overall user experience.

Top 10 Most Used Databases in 2020

1. MySQL

MySQL is a widely popular open-source relational database management system. It offers excellent performance, scalability, and ease of use. With its robust feature set and extensive community support, MySQL is a top choice for various applications, ranging from small-scale projects to enterprise-level systems.

2. PostgreSQL

PostgreSQL is an advanced open-source object-relational database system known for its reliability and flexibility. It provides powerful features such as data integrity, transaction support, and advanced indexing mechanisms. PostgreSQL’s extensibility and compatibility make it an attractive option for developers.

3. MongoDB

MongoDB is a NoSQL document-oriented database that provides high scalability and flexibility. It offers a JSON-like document model, allowing developers to store and query unstructured data efficiently. MongoDB’s distributed architecture and ability to handle large volumes of data make it popular for modern web and mobile applications.

4. Oracle

Oracle is a leading enterprise-grade relational database management system known for its robustness and reliability. It offers advanced features like high availability, security, and data integrity. Oracle’s extensive support and comprehensive documentation make it a preferred choice for large-scale, mission-critical applications.

5. Microsoft SQL Server

Microsoft SQL Server is a feature-rich relational database management system widely used in the Windows ecosystem. It provides excellent performance, scalability, and integration with Microsoft tools and technologies. SQL Server’s enterprise-level capabilities make it ideal for businesses that require a reliable and scalable database solution.

6. SQLite

SQLite is a lightweight and embedded relational database management system. It is widely used in mobile and embedded applications due to its small footprint and simplicity. SQLite offers excellent performance and requires minimal configuration, making it a popular choice for local data storage in mobile apps and other lightweight projects.

7. Redis

Redis is an in-memory data structure store known for its high performance and versatility. It serves as a key-value database and offers advanced data structures like lists, sets, and sorted sets. Redis excels in use cases that require caching, real-time analytics, and pub/sub messaging.

8. Elasticsearch

Elasticsearch is a distributed search and analytics engine built on top of Apache Lucene. It provides powerful full-text search capabilities, real-time data ingestion, and scalability. Elasticsearch is commonly used for log analysis, monitoring, and building search-intensive applications.

9. Cassandra

Cassandra is a highly scalable and distributed NoSQL database designed to handle massive amounts of data across multiple commodity servers. It offers high availability, fault tolerance, and linear scalability. Cassandra is often used in applications that require fast write and read operations, such as IoT, real-time analytics, and large-scale web applications.

10. Firebase

Firebase is a comprehensive development platform that includes a real-time database as one of its core services. It offers real-time synchronization, offline support, and easy integration with other Firebase services. Firebase’s simplicity and real-time capabilities make it popular for mobile and web applications that require real-time data updates.

Factors Influencing Database Selection

When developers choose a database, they consider various factors based on their project’s requirements. Let’s explore some crucial factors that influence database selection:


Scalability is a vital consideration for applications expected to handle growing data volumes or user loads. Some databases, like Cassandra, excel in scaling horizontally by distributing data across multiple nodes. Others, like MySQL and PostgreSQL, offer vertical scalability through hardware upgrades.

Data Model

The data model determines how data is structured and organized within a database. Relational databases, such as MySQL and PostgreSQL, use tables and enforce data integrity through relationships. NoSQL databases like MongoDB and Redis offer flexibility by using document-oriented or key-value data models.


Performance plays a crucial role in ensuring responsive applications. Developers assess database performance based on factors like query speed, indexing capabilities, and caching mechanisms. Databases like Elasticsearch specialize in fast search and analytics, while Redis excels in in-memory caching.

Community Support and Documentation

Having a strong community and comprehensive documentation is valuable for developers. It ensures access to resources, guides, and active support forums. Databases like MySQL, PostgreSQL, and MongoDB have vibrant communities that provide assistance and contribute to ongoing development.


Choosing the right database is crucial for developers to build efficient and scalable applications. The top 10 databases mentioned here – MySQL, PostgreSQL, MongoDB, Oracle, Microsoft SQL Server, SQLite, Redis, Elasticsearch, Cassandra, and Firebase – have gained popularity due to their unique features and suitability for various use cases. By understanding the factors influencing database selection, developers can make informed decisions based on their project requirements.
