A software engineering strategy for client/server applications

To develop client/server applications and software based business processes executable in heterogeneous distributed environments a specific framework of software engineering is proposed. This FAW software engineering strategy promotes a comprehensive architecture for the engineering and execution of client/server applications. Main conceptual principles are: 1. the use of a combination of object oriented concepts and classical data and function modeling for analysis to gain benefits concerning migration and reuseability. 2. implementation of data and functions as separate parts. 3. to provide a platform to administrate and execute this types of objects (data resp. functions encapsulated as objects with a fixed set of access operators). This execution environment should enable transparent access for clients to data functions provided by servers. Explicit models (communications and infrastructure knowledge) have to be used to solve problems of heterogeneity. FAW provides tool support for the strategy by the neutralizing execution environment AMBAS and the engineering environment #OMEGA#mega. AMBAS is a knowledge based implementation of a COBRA compliant request broker architecture which also allows the integration of non-COBRA execution environments and applications. AMBAS integrates client/server mechanisms, transaction management and workflow management. #OMEGA#mega is the Engineering Environment to develop data, processes or applications executable by AMBAS.
