BizSharp is built upon a three-tier architecture:

Presentation Layer, represents data through standard pre - built web forms to be used by the developer.

Business Layer to manage how data is exctracted and modified by stored procedures, web services o custom classes according to reqirements.

Data Access Layer gives access to databases through an interface that instances the different providers available on the market.
Communication between the three layers is totally XML based.

Each layer is represented by a set of classes available to the developer in the implementation phase, to build customisations as necessary. By "default" BizSharp's Presentation Layer presents a set of templates to represent and modify data without necessarily writing code
