By design, dbFront actually needs very little documentation. The primary purpose of dbFront is to hide complexity and delegate all of the real work to your database. So it is likely that most of your questions are actually database related. For database specific documentation, please consult your database vendor or one of the many great Q&A sites on the internet such as dba.stackexchange.com.
That said, we are building a full set of examples showing how to make the best use of your database and dbFront. This includes video tutorials, a knowledge base, and a Question & Answer site. To access these resources, please see our support page.
If you have a question that is specific to dbFront, then please ask. Ask and watch, the documentation will appear, we promise.
