I have all kinds of other guides, but often I find I need to write SQL queries and at the moment I have to try and figure it out by looking at a bunch of data in a column I *think* might be what I'm looking for until I can confirm. If there were any sort of documentation that said, "Hey, the PRASSIGNMENT table holds data about which resources are assigned to which tasks. PRTASKID is a foreign key back to the task table, PRESTMAX is the maximum hours the resource is assigned to the task" etc, that would be EXTREMELY helpful.
