Databases

The RRZ provides database server systems that can be used by University of Hamburg employees upon request. The open source products MariaDb and PostgreSQL are offered. These products are particularly intended for web applications that require their own relational database. However, the RRZ's database systems can also be used independently of a web application for other areas of application in research, teaching, and administration.

MariaDb and PostgreSQL are relational database systems. Queries or operations on the relations are performed using SQL. MariaDb and PostgreSQL are based on a client-server architecture, i.e., the computer center provides the DB servers (RDBMS), which can be used by other systems (web application servers, virtual machines, workstation systems) via a MariaDb or PostgreSQL client installed there.

We will be happy to provide you with information about the MariaDB and PostgreSQL server versions currently in use.
