Yes Amit you're right,
I could see the below lines,
The purpose of the Document CAL is to provide a mechanism by which licensees can license the use of a
single document. To prevent the combination of many data models in a single document, there are
restrictions in the documents that can be used with the Document CAL.
this is a good questions. It depends on the datamodell (a lot of single (loose) tables) and volumes (rowcounts) of these tables as well.
As told above, QT wants to avoid huge applications holding more than one data modell (i.e. Star schemes) for licence reasons.
So best is to contact your local dealer for some test Doc CALs to find it out.
QV works very fine with Star Schemes and the behavouir of the inherit associative data-engine depends on a strong data-modell. So what about a redesign ?
