Configuration Databases (3)

Confdb

• The confdb package provides data access libraries (DALs) which load data from OKS into runtime C++ classes.
• So OKS Objects of Class Module are loaded into objects of C++ class ConfdbModule.
• DALs are useful to provide a convenient user view of the data which may be different from the best way to organise the data in the database itself.
• Also, using DALs insulates you from any future changes to the underlying database product (ie OKS at the moment).
• The confdb package includes a GUI configuration database editor (confdb_gui) which knows about ATLAS DAQ classes and is much more convenient to use than oks_data_editor, though still a little awkward.
