软件体系结构的选择和应用

以社会保险管理信息系统为例,讨论了软件体系结构的选择和应用。整个系统采用具有四层的层次式软件体系结构的设计思想,在业务管理层的设计中,采用了互连系统构成的系统(SIS)的体系结构,把整个业务管理系统划分为八个从属系统。各从属系统的体系结构可以相同,也可以不同。这种体系结构设计有效地降低了维护成本,提高了系统的开放性、可扩充性、可重用性和可移植性。

Selection and Application of Software Architecture

Selection and Application of software architecture is discussed and applied in a social insurance management information system.Layered software architecture is used in the whole system,and architecture of systems of interconnect-ed systems is used in the design of business management layer.This layer includes eight subordinate systems ,and the software architecture of a subordinate system may be the same with others or not.For example,orthogonal software archi-tecture is applied in a subordinate but C/S and B/S hybrid software architecture is applied in another subordinate.This design method of software architecture can save the costs of development and maintenance efficiently,and improve open-ness,expansibility,reusability and portability of systems.
