摘要
该文介绍了面向对象的建模语言-统一建模语言(UML)的基本定义和建模机制。根据UML的建模原理,研究设计了网上审批系统的软件模型。在模型的基础上,利用Java2企业版的三层结构实现。实现过程表明,利用UML对复杂的软件系统建模,有助于详细分析需求,优化开发人员对中间层即商业逻辑层的设计,实现软件的重组和复用。
This paper firstly introduces the basic principle of UML, which is called the Unified Modeling Language, and explains how to set up the model with UML. Then, it mainly shows the process of establishing the model of the Examining & Approving system on the net with UML in detail. Finally, it discusses the key principles that implement the system in three ties from UML to Java 2 Platform Enterprise Edition. Setting up the model with UML can help the designers to analyze the requirements of the complex system, and help the designers optimize the middle-layer's designing, realize the software's reuse and reconstruction.
