Configuration Databases (2)

OKS

• OKS is very general, no knowledge of ATLAS.
• The database is implemented using a few generic classes, eg:
  • Class: class defining database classes and their attributes (ie the database schema). An instance of a Class object describes one class, eg Module.
  • Object: class holding instances of a Class class (ie the database itself).
  • various others for data members, relationships, etc
• Many (federated) schema and data files can be loaded.
• The API provides various queries to locate objects, etc.
• OKS provides two GUI editors (both a bit cumbersome):
  • oks_schema_editor: to edit the database schema, basically to create and modify Class objects.
  • oks_data_editor: to edit database data files, ie create, modify or delete Object objects.
  • Since both commands need to be given all the relevant schema files, the command lines can be very long. In my script setup_l1calo.sh I define some useful aliases: edschema and eddata.
