Applied Research, The Field Of Engineering In The Online Review System

Domain engineering is a key technique to achieve systematic reuse. It does not only establish the reusable software assets for specific fields, but also offers the systematic method to implement them. Supported by researching methods in domain engineering, this thesis takes out domain analysis and domain design, thus provides basis for the systematic reuse in network-evaluation fields.Having discussed current research of domain engineering then combines the UML(Unified Modeling Language) and feature-oriented domain analysis, so as to practice analysis of network-evaluation domain in its features, knowledge and operation, which finally set the model of network-evaluation domain. Then abstract the features both the enforceable and not on the ground of the domain models. According to the principle of loosely coupling and tightly polymerizing, then gets the main components in the domain and structures well-arranged software model of network-evaluation on that basis.The thesis offers an easy-assembly software component model, and describes the component model interface configuration information; it also analyzes the role of that information in the process of assembling. Finally according to the basic framework of the component assembly and component model, the thesis describes the component assembly process in detail with XML.The network-evaluation system researched in thesis provides economic, efficient, fairly, justice and open management and monitor mechanism for the scientific and technological assessment, which also improves both the efficiency of office work and the quality of service management. The applied research of domain engineering in network-evaluation guarantees the reuse of network-evaluation software and improves the productivity and reliability of the application system of network-evaluation.
