高层管理信息系统涉及的信息类型多、结构复杂，对用户界面的要求高。常用的关系型数据库管理系统所提供的图形设计能力很弱，影响了系统开发工作的效率。在一个实际系统的设计中，我们采用面向对象技术分析用户界面，定义出界面的各种对象和信息模型，提高了图形用户界面程序的可重用性，缩短了系统开发周期.

In a top management information system, the information media are colorful and the data structures are complicated. Meanwhile the users have high expectation on man machine interface. The normal data base management systems can provide only low capacity for graph interface designing. This factor declined the efficiency of system development. In the design of a practical system, we used the object oriented systems analysis (OOSA) technical for user interface designing, defined objects on the interface and set up an information model. According to this method, we improved the reusability of graph interface programs and shortened the system developing period.
