DAL中存储过程映射的分析与设计

Analysis and Design of Mapping of Dtored Procedure in DAL

DAL是以ORM为理论基石,实现业务逻辑层中的数据对象与数据库中表之间的映射,从而为存储过程与数据对象之间映射奠定理论和实践基础。在分析DAL映射基础之上,针对存储过程返回结果集的复杂性和不确定性,提出存储过程映射设计方案,并在项目中得到广泛应用。

ORM is theoretical base of DAL, which accomplishes the mapping between the data object business logic layer and table in database. So, it lays a theoretical and practical foundation between stored procedure and database. On the basis of analyzing the mapping of DAL, puts forward the plans of stored procedure according to the complexity and unfeasibility of the results collection of stored procedure, and applies it broadly to the projects.
