missing field descriptions in the datamodel documentation

I'm missing datamodel descriptions e.g. of fields in the tables and how to use them e.g. what values means what in the status or in the prio field in the JOBS table. Today where we have an external database the information is very important, if the you want to run some SQL adhoc or for reporting. You have currently to debug or comparing GUI informations with values in the fields. The visual part of the datamodel is also important for a fast overview of table dependencies etc. but it could otherwise perhaps be generated by a another tool like Erwin or other.

It is important that the SQL create script is well documented for superusers or dba's.
