Host
The host synchronizes different parts of your application. In other words, it acts as the model (by storing and persisting your application's state) and as the controller (by providing a variety of convenience functions to modify the state).
Visual Module
A visual module:
- gives a SQL query (or several) and receives data
- receives an HTML container and renders in it
- gives parameters definitions and receives parameters values
