Design & Realization Of The Teaching Test & Evaluation Domain's Component Library System

With the development of software engineering, software development process based on the components reuse becomes the researched hot point. The component library system as an important establishment to provide services for component-based software development process has been concerned widely by the researchers. When a software team is developing the software system in an application domain, the component library system is more needed to help them to accumulate domain knowledge, and to accelerate the domain evolvement.In this paper, under the background of teaching test and evaluation domain, a component model is presented, and the teaching test and evaluation domain's component library system in support of team development is designed and realized. The created works of the paper are listed as follows:1. The component model describes the component from the semantic element and syntax, which makes it easy to understand the component. The component model is able to describe the domain characters of a component, which can help to understand the component reuse possibility based on domain.2. Domain description tree is introduced in this paper. Domain description tree provides the method to realize the description of the component domain characters, and to record the domain changes in time for accumulating the domain knowledge.3. A strategy to recommend component is introduced. The change of the component reuse possibility and reuse rate can be reflected in time based on it. It may guide the users to choose the component and accelerate the domain evolvement.
