Analysis and Design of Ecommerce System based on UML
——Modeling Net Ordering System with UML
Abstract
In the development of object-oriented software, if the software consists of hundreds of objects, it is difficult to understand the relationship among them by simple analysis. Meanwhile, to facilitate the maintenance and code reuse of large or medium-sized software, establishing a model before specific coding is necessary. UML(Unified Modeling Language), a modeling language developed based on a lot of object-oriented modeling methods, is a universal visual modeling language used for describing software, visual processing, constructing and establishing the documents of the products of a software system. It is now the standard modeling language in software industry and is mainly used for analyzing and designing a software-dense system. This paper explores the issues of object-oriented analysis, designing, implementation and so on in UML, by taking Ecommerce system as an example. We elaborate on the requirement analysis of the net ordering, determine the domain Diagram of the system, establish the system architecture, and present the detailed design model(static model,dynamic model and physical model) based on the described Use Case. Also abstractly introduced is the relevant knowledge of UML and iterative development.
