When a 4GL client updates a record in the database, the actions taken behind the scenes are quite a bit more complex than you might imagine. In this talk, we describe what happens in the 4GL client and the database when executing a simple 4GL program. We will look at compiling, client side data structures and the various operations that take place on the client side. Then the actions performed in the database.
