The basic features allow most simple queries to be done very quickly, however building more complex queries can be done using the methods listed below, which append or set conditions that build the query.

The DB_DataObject can now handle JOIN queries, however please read the introduction to linking and Joining before jumping in and using the Join feature, as you may be trading the use of a cool feature, against the readibility of your code.
