电子文件归档管理系统的核心功能单元设计

以数据导入单元的设计为例，阐述了电子文件归档管理系统核心功能单元的设计思路。主要从建立功能单元工作流程和确定逻辑操作及逻辑处理出发，就对象模型建立、类定义与类间关系、操作功能逻辑实现以及单元功能测试等方面进行了论述。

Core functional unit design of electronic document archiving management system

Taking the design of data import unit as an example, we explore the design philosophy of the core functional unit of electronic document archiving management system. Based on the establishment of a functional unit working flow and determining the logic operation and logical processing, we discuss object model establishment, definition of a class and relationship between classes, logic implementation of operation function, and unit functional testing.
