Research And Implementation On Domain Engineering-Oriented Administration Of Work Safety Software

With the rapid extension of computer application domain and continuous increase of software cost and complexity, the requirements in various aspects of the software have been improving. How to continually improve the quality of software products and the software productivity has become an urgent to address issue. Learn from the experience of other traditional industries, software reuse as an effective way to solve software crisis has been more broad attention. To further enhance the rate of software reuse, this paper will focus on a specific domain of Administration of Work Safety Software. There is a universal similarity in the domain, however, variability in this domain is also an important feature. How to effectively depict the variability and invariance and how to extract the domain component becomes a hot area of Domain Engineering.This article analysis the domain of Administration of Work Safety with Feature-Oriented Domain Analysis method. Feature is used to describe the characteristics of the variability and invariance of the domain. Based on feature model of Administration of Work Safety, analysis the character of samples system of domain, explained the invariability and variability of the domain, established feature model of Administration of Work Safety and soft structure with four ties, UML modeling technology, and EJB component technology was applied to the process of design and implementation of the domain. At last, a typical sample of domain was given to show the process of component assembly and deployment, and how to achieve the purpose of software reuse.The applying of domain engineering makes foundation of software reuse based on component in Administration of Work Safety domain. The component can avoid much duplicated work and also provides a reference for software reuse based on component in other domains.
