Widespread Open Supply Databases for Linux


Selecting the best database service typically depends upon what you want it to do. There are various free and open supply database options that you need to use, however just a few have risen to the highest in adoption and efficiency.

At no cost, general-purpose relational databases, you’re probably contemplating MySQL and PostgreSQL. As their names clearly state, each programs assist the Structured Question Language (SQL). Though the small print of every are a bit of totally different, the recognition of SQL as a normal question language means you’ll discover loads of sources, documentation, associated tooling, and even different builders if wanted to assist your app.

Relational database programs like MySQL and PostgreSQL are closely structured, that means the information is saved in a highly-organized type, making it straightforward to question later.


MySQL is a foundational element of the LAMP and LEMP stacks, utilized in content material administration programs and different purposes. MySQL is optimized for database reads, that means it really works greatest when information will get queried continuously and new information will get added much less typically. That is frequent conduct for databases supporting general-purpose web sites, ecommerce websites, and listing purposes.


PostgreSQL is taken into account extra versatile and complicated than MySQL, with a wider vary of knowledge varieties and extra superior queries. This could additionally make PostgreSQL more difficult to implement, relying in your utility. Regardless, in case your utility is write-heavy, that means it’s extremely scalable, is high-volume, or is an “enterprise” utility, PostgreSQL is an efficient alternative.

There are additionally NoSQL programs that retailer information in a largely unstructured format. Though it takes a bit of longer to get a question response, a less-structured format permits for a lot quicker write processes to a NoSQL database. NoSQL databases are perfect for conditions the place you wish to add or transfer information to the database shortly and aren’t involved a couple of standardized question language to retrieve your information sooner or later.


MongoDB is the preferred NoSQL database and options graph search, geoSearch, map-reduce queries, and textual content search. MongoDB is good for gaming, IoT purposes, personalization engines, and different purposes the place the information doesn’t simply translate to a extremely structured or schema-based mannequin.

Two different database choices, Redis and Cassandra, goal extra specialised workloads or purposes.


Redis is an in-memory database with a key-value construction. As a result of information will get saved in reminiscence, it’s accessible for high-speed searches and behaves extra like a cache than a standard database. Redis is commonly used with high-demand stock programs and different purposes that require a lightning-fast response time. Though information is accessed from reminiscence, Redis invisibly retains a document of the information on disk for restarts and to stop information loss with system failure.


Cassandra is a NoSQL database system that makes use of its personal question language, the Cassandra Question Language (CQL), which has similarities to SQL. Cassandra is designed for distributed environments and is very resilient to outages and information loss. When it comes to scalability and efficiency, Cassandra has been examined on clusters of as much as 1,000 nodes, and comes with different instruments to assist bigger installations, together with auditing, replication, and assist for elastic clouds. 

Whether or not you’re organising a easy web site, constructing a distributed information retailer, or making a customized enterprise utility, we may help with documentation to assist open supply database choices to deploy right now, or managed options to assist make the method a bit of simpler.
