Data plays a very crucial role in modern businesses. Both global enterprises and non-profit organizations depend on data to obtain their target in today’s world. A robust database management system is thus essential for storing, retrieving, and manipulating data. Several database systems exist for operating on different types of data, and robust data management mechanisms are also available to help with this process. Since Linux plays a significant role in the modern-day business and software ecosystem, a vast array of robust database management systems for Linux exist to help developers leverage data effectively.
Database vs. Database Management Systems(DBMS)
Often we see many people getting confused with the difference between traditional databases and database management systems(DBMS). As a matter of fact, we all have been there where it just didn’t make sense. So, we’ll try to distinguish between them below.
A database is a software that stores data. Examples include MySQL, Microsoft SQL Server, and such, whereas DBMS refers to software that allows users to retrieve these data and manipulate them as per their requirements.
The confusion arises because many DBMSs, such as MySQL, pack pre-built mechanisms for managing the data in their database. Others only offer the database, no management methods. You need to understand that a database management system is not just the database itself but rather a collection of utilities packed together with the database.
Best Database Management Systems
Since a plethora of powerful and rewarding database management systems for Linux exists, we tried our best to select the ones with the most use cases. Our editors have picked different systems for different types of databases like DBMS for relational databases, object databases, document-oriented databases, etc. Hopefully, you’ll get a good overview of the choices in general.

SQLite is arguably one of the most innovative and empowering database management systems for Linux. It is based on SQL and takes a relational data management approach. SQLite is different from conventional Linux database management systems because it does not follow the traditional client-server database engine. Instead, this open-source database management system is directly embedded into the final program. Thus, it is a popular choice for developers who want to pack the database right into the software.
Features of SQLite
- SQLite is exceptionally lightweight, measuring at 699 KiB, and thus can be loaded directly with software without adding redundancy.
- It stores the entire database, including tables, indices, and data, as a single file on the host machine and does not require any service management.

- Amazon RDS provides easy administration features for your databases, such as the RDS management console, RDS command line, and a robust set of APIs.
Redis is a robust, in-memory, and open source database management system for storing key-value pairs. It is usually used in caching and has been widely popular due to its lightning-fast speed. Contrary to traditional Linux database management systems, Redis doesn’t save HDD data. It stores the key-value pairings in the RAM. Since accessing RAM is much faster than accessing HDD or SSD, Redis is among the fastest database management systems for caching.
Features of Redis
- Apart from the flexible desktop GUI, Redis has interface support for C, C++, Erlang, Haskell, Java, Perl, PHP, Python, R, and Ruby.
