database development in london - How does sub-documents work?

A Subdocument is an embedded data set. So you have your primary data, for example a list of clients. Your subdata set could be a table or query containing anything relating to these cleints, perhaps purchases. So when you link the subdata to the primary data you can view the related recoards more easily.

An example might be a subform. Here your main form contains the client data fields and the subform contains the sales. As you scroll through the cleints records, the subdata will change according to the current client record.


Does that cleirfy it for you?
