Research and application of methods of developing industry- domain system based on software reuse

Software reuse can improve the efficiency of development and reduce the costs of maintenance. It´s particularly effective in the domain of specific industry. This paper studies the methods and procedures of software reuse used in the development of the domain specific of industry. In accordance with the development process, requirements analysis, system design, system implementation, use respectively the domain analysis, chromatographic analysis and architecture design, component technology, establish the demand model of the industry domain, the architecture model of the industry system and develop the system with components with an example of project cost industry. This paper verifies the method of software reuse development, proved that the demand model of the industry domain, the architecture model of the industry system and components have high reusability and scalability in the same industry, meanwhile the method greatly improves the efficiency of software development in industry domain.
