摘要
Client/Server体系结构和Browser/Server体系结构是目前应用较为广泛的两种软件体系结构,在分析两种体系结构各自优缺点的基础上,提出将两种体系结构结合而形成三层混合体系结构。这种混合体系结构由表示层、业务层和数据层所组成,表示层对应某一具体应用需求并负责用户的交互,业务层负责将表示层提交的用户的需求转化为特定服务器的基本功能,数据层用来存储数据和提供基本数据服务。广东省水资源综合规划信息系统(WIPIS)便是三层混合体系结构的典型应用,系统具有开放性强、易扩展,开发和维护成本低等优点。
The Client/Server and Browser/Server software architecture are widely used home and abroad in recent years. Because each one has flaws and virtues, an idea is brought forward that is engaged in drawing virtues from both software architectures and discarding their flaws to present a mature three-layer hybrid software architecture, namely, presentation layer, business logic layer and data layer. The Water Resource Integrative Planning Information System （WRIPIS） of Guangdong province is a typical application of three-layer hybrid software architecture. Some functions are achieved in the system, such as, pre-warning water shortage function, graphic-attributes exchange query function, making GIS thematic map function, etc.. The realization of the WRIPIS makes it clear to use the hybrid software architecture to develop information system with better opening and expansibility. This can save the costs of development and maintenance.
