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
