Running DBD for specific group of table

HI,
The Designer has two modes, Comprehensive and Query-specific. Comprehensive does a complete set of projections based on your existing design. Query-specific only does a set of projections for the table(s) in the query/queries provided. So if your query is on a single table then it will only do projections for that table. If it involves multiple tables it will do projections for all tables referenced in the query. 

Hi!
