通过PowerDesigner实现公交系统的初步设计

The preliminary design for vehicle managing information system by Powerdesigner

利用 Power Designer对河南省机动车管理系统的需求分析及总体设计模型进行仿真 .在需求分析中弄清系统开发的软、硬件环境及目标 ,在此基础上完成系统流程图、系统结构图、实体关系图的设计 ,讨论数据字典的构造 ,实现了数据模型的创建及相应的标准概念模型报告的生成和物理模型的生成 .对如何利用快速原形法开发工具 ,把物理模型转化成 Power Builder程序进行了展望 .

PowerDesigner is used to emulate the model of requirements analysis and general design of He'nan vehicle managing information system. Software, hardware of MIS and the aim are recognised in requirements analysis, on the basis of which, the Data Flow Diagram, the system construction drawing and E R Diagram are designed, and the construction of Data Dictionary is discussed. It has achieved the make of the data model(E R Diagram), the product of the Standard PDM report and the make of the physics model. At last it is forecasted that you can change physics model into a PowderBuilder program through AppModeler(a kind of rip tool).
