Abstract: Software reuse for software architecture is a certain demand on mass production of software for computers. This paper discusses a software architecture based on patterns, which is a multi-tiered distributed system’s structure by technique of Borland Data Snap. In this scheme, business logic layer is encapsulated by an expanded “Facade”, and remote data module is optimized by using two-object pooling.

Key words: Patterns, Architecture, Multi-tiered distributed structure, OOP

摘要： 软件架构的复用是大型软件生产的必然要求。该文讨论了一种基于模式的软件架构，它是在Borland的Data Snap技术的基础上建立起来的多层分布式架构。在此方案中使用扩展的门面模式封装业务逻辑层，使用双对象池对远程数据模块进行优化。
