Model View Controller

IntraWeb uses the Model View Controller design paradigm. This design paradigm separates internal logic, user code, and presentation layer into separate pieces.

MVC Crash Course

If you are not familiar with MVC, here is a crash course:

• Controller - Provides internal application direction and flow. Interprets external input and routes information to appropriate model code.
• Model - User code. Normally this consists of many separate units that are connected to the controller.
• View - Code or data that is used to provide the user interface.

Many detailed overviews of the MVC design paradigm can be found by searching for "MVC model view controller" in Google.

IntraWeb and MVC

IntraWeb provides all the functions of the controller layer transparently to the developer. The user code is written by the developer and resides in the model layer. The view layer is provided by a layout manager. In many cases no explicit layout manager is specified by the developer. In such cases it may appear that there is no separate view layer, however IntraWeb maintains the layer separately by creating an implicit default layout manager.
