The Business Objects Framework (BOF) is built into DFC and helps developers create reusable business logic components called Business Objects. Applications using DFC can access BOF easily and can use BOF as pluggable components/entities in middle-tier or client applications. Let's take a simple example to understand this.

Assume that you require a specific business functionality of performing some particular validation whenever a particular document of some particular object type is checked-in into the Docbase. This can be achieved by using BOF and overriding the check-in functionality for the particular object type. Once written, the same business object is called irrespective of the client application used—be it Webtop, Web Publisher, some Desktop application, or some custom DFC class for that matter. In short, what we achieve is a reusable component/functionality.

There are two types of Business Objects:
