基于代码下移的分布式软件框架

Distributed Software Framework Based on Code Down

在通用3层结构框架的基础上,利用公共语言运行时,设计并实现一种分布式软件框架。该框架将业务逻辑层中的部分代码下移,并在数据层中增加存储过程调用子层,从而降低网络数据传输量,提高分布式环境下软件的运行效率。以某大型制造企业工时定额系统中的分工表展开模块为例,详述该框架的构建过程,验证了该框架在提高软件整体运行效率方面具有普遍适应性。

This paper uses the Common Language Runtime（CLR）, designs and implements a distributed software framework based on the common three-layer structure framework. This framework puts some codes of the business logic layer down to the DataBase Management System（DBMS）, and adds the sub-layer of calling stored procedure which can reduce the data traffic of network and enhance the performance of the application in the distributed environment. It takes the expanding division-table module of the task time quota system in a large-scale manufacturing company as an example, expatiates the building process of this framework, and verifies the general adaptability of the framework in improving the running efficiency of the overall application.
