The controller is a Java program that is used to glue UI (view) and Data (model) together.
For typical database access, the glue logic (i.e., control) can be handled by a generic feature called Data Binding. In other words, the read and write operations can be handled automatically by a generic Data Binding, and you don't need to write the glue logic at all.
In this section we will discuss how to implement a custom controller (aka., a composer).
