摘要
业务逻辑基础类库的编码实现是整个逻辑层实现的核心,如数据库连接类和系统设置类以及购物车信息类。它可以通过具体各模块的界面和后台编码来实现。本文对一个电子商务应用系统——网上书店进行了需求分析、概要设计、详细设计实现,初步建立了一个网上图书店。
The realization of the entire logic of the core layer, such as database connection type and category of system set- tings, as well as the type of information to Cart can be achieved through the concrete realization of the interface of the module design and the background coding, based on business logic class library code. E - business applications on a system - online bookstore are discussed, analyzed and designed in this paper and a web - based bookstore is established preliminarily.
