| Object Oriented Technique has replaced the traditional Analysis and Design technique and set up as the main technique in software engineering. UML (Unified Modeling Language) is a kind of modeling language, which has became a kind of standard language in the domain software industry. UML, which adopts the new conception, method and technology in software engineer, is fine defined, easy expression and powerful in function. It can be used in the field of object-oriented analysis and designing, and also can be used in the whole process of system development. In order to standard the process of modeling, we import the Rational Unified Process (RUP) in system development process. UP provides the method of how to assign assignments and responsibilities in development process and it used to unifying the way how the UML used under certain framework and process guiding.This paper researches the process of analyze and design for Import and Export operation System with using UML and related Rational Unified theory. The first step is to analyze the import-export (IE) operators' requirement. By using control theory, IE's workflow can be looked as a feedback system. With researching import, export and return shipment operator's work, it is quite easy to get all of IE relative requirements for enterprise. After analysis these requirements, the system's Boundary Model and Question Field can be confirmed, so we drew up all of requirements with the Total Use Case diagram. The second step is to rediscribe the Total Use Case diagram and realizes requirements with software's language. By drawing out Use case diagram, Class diagram, Object diagram, Package diagram, Static diagram, Dynamic Behavior diagram and Deployment diagram, we setup the logic system analysis, which includes how to describe the attribute, operation and correlation among objects and how to define time characteristic and communication mechanism for finish the target of objects. The third step is to design the system's structure and Database. With using Component diagram and Deployment Diagram, the physical system's structure Modal is finished, which describes how to describe system's module, physical conformation and organization, and node's distribution in the system. We use Oracle9i as database software, design and criteria some import database sheets. At the last chapter, some interfaces are showed, which stand for the real function for the system. The system was used in Business field by Beijing Jietu Trading Inc. Until now, it has handled 2000 orders successfully and got high appraise from users. |
