Distributed Software Architecture And Enterprise Application

As the size of enterprise and complexity of software system increase, the design and specification of overall system become more significant issues than the choice and design of specific algorithms and data structures. As a means of representing the system design at a high level of abstraction and implementing the software reuse in a widely area, software architecture is one of the hotspot in software engineering field.In this paper we first present the definitions, origins, research directions and importance of software architecture, dissertate distributed software architecture. The dissertation introduces the concept of workflow management system, an important method to implement business process reengineering (BPR). On the basis of Domain-Specific Software Architecture (DSSA) andResearched chief, we develop a DSSA-based ERP model-ERPSA2.0and its development circumstances, and at last introduce an actual software system used ERPSA2.0.We discuss the model in detail, bring forward tier-analyse method of enterprise model and function-interface method of business. Based on resumption of software architecture, develop a series of especially function module relate to domain, currency function module and assistant development module.
