Uml Modeling Strategy For Database Application Systems

Based on the principles and target of software engineering, this article attempts a comparatively deep research on modeling methods and modeling strategy and steps with UML, develops a real gate card-settlement system for a computer center of a tertiary education institution. This article mainly discusses how to correctly select software factors, the modeling methods and modeling strategy of evolution of modeling from logic to physics and the modeling strategy of improving the efficiency and agility modeling.Meanwhile, Bases on the study on UML modeling process and through application, this article shows a framework--"UMP" that is interactive with RUP. Using the above mentioned modeling theory and modeling organizing strategy and with the help of ROSE tool and UML language, this article achieves a complete analysis and design modeling for the metering system of computer lab.Within the process of modeling, using UML language extension mechanism, this article puts out the "Transaction" for data base application system, and the modeling canonical means of "Data set" and "Data table". Through reverse engineering, this article conducts a study on the data base connecting target modeling which is back staged by SQL Server2000 and achieving c/s mode, and discusses the evolution process of modeling bottom from analysis mechanism to design mechanism. This makes the enriching and detailing model be directly effective to the programming activities.Finally, using the Delphi developing tools, this article achieves object-oriented code programming and successfully uses the Component-based development technology and multithreading programming technology on RFID Radio Frequency Identification subsidiary system.
