这个项目包括数据访问层、业务层和用户接口示例“联系人管理系统”。这个项目的目的是引导用户做模块化编码和知道如何重用通用数据访问代码使用业务层。步骤————————————————————————————————————————————————————————1。创建数据库和表结构通过运行脚本中提供“\ \数据库创建脚本查询”文件夹。打开联系人。sql文件在“查询分析器”和按F5 2。从TableData_tbl_mst_Contacts运行查询。 txt文件从“\查询”文件夹中使用“查询分析器”3。从TableData_tbl_mas_Contact_Category运行查询。 txt文件从“\查询”文件夹中使用“查询分析器”4。更改连接字符串从Web。配置文件5。打开项目并运行它-The project includes the data access layer, business layer and user interface example, " contact management system."　The purpose of this project is to guide the user to do a modular code and know how to reuse common data access code to use the business layer. Step-------------------------------------------------------- 1. Create a database and table structure is provided by running the scr ipt " \ \ query the database creation scr ipts"　folder. Open Contacts. sql file in the " Query Analyzer"　and press F5 2. From TableData_tbl_mst_Contacts run the query. txt files from the " \ query"　folder using the " Query Analyzer"　3. From TableData_tbl_mas_Contact_Category run the query. txt files from the " \ query"　folder using the " Query Analyzer"　4. Change the connection string from the Web. Profile 5. Open the project and run it
