Portals in Application Integration

Abstract

Integration is widely used in different areas, but few are explained. A common understanding is that integration is a process by which parts of a whole become more connected so that they are, in effect, less “part” and more “whole”; that is, such that functions formerly carried out by one part are carried out by others and usually vice versa. Normally, in the IS area, we use integration in such a case: formerly separated or loosely connected parts are expected to be considered as whole, then we need approaches to connect them more tightly, and at the same time, functions in the “new” system are redefined and redistributed to “new” parts.
