Field Of E-business Modeling Method Research And Application

The key criterion to evaluate a software project is the user's requirement is met or not. Requirement is an interactive process of developers and users. A project won't success without the cooperation of any part. Business modeling is the foundation of the requirements. It is a tool and a result for developers and users to communicate the requirements. Users are not necessarily software experts, but they are business expert. So business modeling becomes the key point of expressing requirements and understanding project scope.The history of business modeling is introduced in the paper firstly. Against the big requirement problems due to ignoring business modeling, the importance of business modeling is analyzed. According to the characteristics of e-Government, an extended modeling language is researched as business modeling language based on standard modeling language UML. Business modeling principles, business modeling process and four general business models, including business objective model, business organization cooperative mode, business resource model, business process model and business use case model, are provided and studied. The innovation of the paper is to build a e-Government oriented modeling method based on domain engineering. Domain engineering is used as core method to extract abstract e-Government business for business modeling.It used Object-oriented technology and UML based standard modeling language in the paper. Using Object-oriented technology in modeling process will standardized users' thinking and description because it is a wide-accepted thinking way. Using UML in business modeling will consist with the tools or expression method using in following software processes such as requirement analysis and system design. All the advantages will guide the following software processes better.The value of the paper is to design a practical and operable business modeling method for e-Government area. It will provide a template for business modeling development for the same type of projects, which has great engineering value.
