Databases

This article is about choice of database models and implementations.

Copyleft free to modify and free in cost software is strongly preferred over other solutions. Minimal modifications required could be another preference as that means maintenance of the chosen solution is minimized in that aspect.

Known types of databases

Relational database

Together Consumerium and Consumium run all the 3 major free full fledged RDBMS there are: w:MariaDB, w:MySQL and w:Postgresql.

Relevant relational database powered software

  • MediaWikis run on w:MySQL or the better and more ethical binary compatible drop-in replacement w:MariaDB. A recent fork by the original MySQL founders from MySQL.

The Netherlands server serving the Consumium free social media run on MariaDB 10


Subject-predicate-object database

Subject-predicate-object databases basically construct w:semantic networks from interlinked atomic units called a w:triplet so they are not fundamentally different from graph databases in functionality and utility offered.

These networks may be queried with a suitable query language such as w:SPARQL which in practice allows you to compose semantic queries.

Relevant subject-predicate-object database powered systems to interoperate with

Things to consider in selection of triplestore

A w:triplestore maybe a native implementation from ground up or be standing on the shoulders of a standard RDBMS system where actual w:SQL is formulated by the interpreter and then queried from SQL. This probably has upsides and downsides.
