Introduction to the Database group.
For more than a century GEUS has compiled geological data. These data have been electronically processed since the late 1970s, at first by using punch card based systems, later "main frames" and now in relational databases.
The Database group was established in 2001 and consists of 14 persons who develop databases, dynamic home pages, web services, programs and mobile Apps.
GEUS' central database is based on Oracle, but the group also uses PostgreSQL, Firebird, MS SQL Server and the SQLite databases, as well as the spatial extensions Oracle Spatial, PostGIS and SpatiaLite. For developing Java and Delphi are the primary tools.
The main task of the Database group is to secure that GEUS data are stored centrally in a well-structured way, and made available for GEUS' staff, co-workers and the public. Some data are provided free of charge at GEUS' homepage, through different web services and as download of whole databases. The Database group makes solutions for internal users as well as external customers.

Selected systems:

The database group maintains among others the following systems (mainly in danish):

  • Jupiter: the national database for geology and ground- and drinking water
  • GERDA: the GEophysic Relational DAbase
  • SAMBA: the database for storing oil- and gas related data

The Database group works closely with the GIS group concerning the development of map-interfaces to be used with the databases see for instance:
