BRE utilizes the so-called hub and spoke principle to reduce integration complexity and eliminate unmanageable relationships between the various system components. The interface with BRE, the so-called Business Request, is defined on a business level to make the client fully independent of the internal specifics of the back end server systems. A developer of a BRE client can use the standardized, easy to use BRE interfaces to develop and deploy an end user application in a very short time. Transformation BRE provides a standardized object oriented interface on the client side. A format transformation is then made within BRE between the Business Request and the various interfaces of the core application systems and the request dispatched.
Integration BRE isolates a Business Request from the processes of the back end systems.
One Business Request could comprise accesses to several core applications. Delivery of all Business Requests to their target systems is guaranteed by the communications protocols used. Server Adapter BRE offers adapters to various ZKB applications. The logical co-ordination of communication and any application specific handling with the server is made within the adapter. In an error situation the responsible area is alerted automatically via the existing problem management infrastructure.
