Object references in general are one-way only, right? Is it technically impossible to directly navigate from detail to master, then. Find all purchase orders with item #12 on the list. Oh, I forgot, oodb will bring all the orders into memory...

Unless, oodb starts maintaining double-linked references, you can't claim that it could easily match quering capability of relational. And adding double-linked references to object model compromises the simplicity that object folks are emphasising. Received on Tue May 08 2001 - 18:58:40 CEST
