基于用例的装备保障数据仓库功能设计

为了解决装备保障数据仓库构建中功能设计这一难点问题，采用用例的方式对其功能体系进行描述。通过UML用例图，建立起决策支持功能、业务功能、运维功能的装备保障数据仓库功能体系，并对相关要素进行说明。用例图直观地展现了数据仓库功能，极大地方便了用户与开发人员之间的沟通，提高了装备保障数据仓库开发过程中功能模块的设计效率。

On Use Case Diagram Based Equipment Support Data Warehouse Function Design

In the process of building equipment support decision data warehouse, it is a big problem to describe the need of functions. In this paper, we use UML use case diagram to design the functions of equipment support data warehouse. The function architecture including decision making functions, business functions and operation functions is designed. Use case diagram describing functions as a direct view, is easy for users and designers to communicate. This method improves the understanding of system function needs, and is meaningful to the system development.
