Introducing I/O Channels into the Device Database Opens New Potentialities for Configuration Management {*}

T. Birke, B. Franksen, R. Lange, P. Laux, R. Mueller (BESSY)

The reference RDBMS for BESSY II has been set up with a device oriented data model. This has proven to be adequate for e.g. template based RTDB generation, modelling etc. But since names and meaning of assigned I/O channels are stored outside the database (1) numerous specific conditions have to be maintained within the scripts generating the configuration files (2) several generic applications that require a larger and structured set of channels can not be configured automatically by scripts. In a larger re-design effort the I/O channels are introduced into the RDBMS. That modification allows to generate even the more exotic types of RTDB out of the RDBMS, map specific conditions into database relations and maintain application configurations by intrinsically generic extraction scripts.
