An Analysis and Design of a Provincial key Laboratory Management System

本文讨论了一个省级重点实验室管理信息系统的需求分析和概要设计。采用结构化分析的方法,描述了一个省级重点实验室的日常事务模型以及概要设计。列举了自然语言描述的需求分析,并相应给出了具体模型。基于具体模型,画出了分层数据流图,并对该数据流图中的加工做出了说明,给出了数据字典。最后,根据数据流图,设计了系统的结构模块图。

This thesis discusses the requirement analysis and structured design for a MIS of a provincial key laboratory. Adopting structured analysis methodology, it describes the daily transaction model and structured design of such a laboratory. The author enumerates the requirement analysis by natural language , and presents the detail model. For that detail model, the author draws the DFD, and describes the actions on the DFD. The corresponding data dictionary is also given. Finally, the author designs the system structure module diagram based on the DFD.
