摘　　要：采用ADO.NET默认结构,数据库操作和数据校验程序位于同一个.cs代码文件中,使得程序结构不清晰,因此,有必要按装配件设计思想对ADO.NET默认结构进行重构,把数据库操作和数据校验功能从Web业务逻辑层进行分离而封装为一个通用的数据接口装配件。同时,基于装配件的分解思想,将任一个Web应用分解为业务层、业务规则校验层、SQL语句生成层和数据对象实体层,并给出业务层中的促销入库业务类调用该装配件的方法。应用实践结果表明,该装配件具有良好的通用性,且大幅缩短了开发周期。According to ADO. NET default, the program structure is vague, which data operating and checking function are located in the same .cs code file. Thus, on default structure of ADO. NET based on analyzing idea of assembling is improved, A universal data interface subassembly of packaging database operation and the data checking ftmction is designed and realized. Besides, this text decomposes any web application into business, business rule check, SQL and data entity layer, and presents the means of calling this data interface subassembly in business layer of sales promotion. The application proves that it has fine universal and shortens development period.
