Research And Design Of Software Product Line Based On Component

Under the situation of computer being used at every corner of social deeply, the software development is growing up from small-scale and utility-style Pattern to large-scale industrial chain mode. In this process there ware created a lot of ideas can guiding the direction of future development in the software industry, some of them in the technology area and some in business area, and the software product line technology is the representative in technology area. While this thought is not currently widespread in domestic software development, it is only supported in the field of theoretical study, but in the foreseeable future will certainly further the development of domestic software standardization and scale has a positive far-reaching impact.This paper introduces the development of software engineering, and describes the theoretical basis for software product line-software reuse at first. Then discusses the concept of software product line technology and composition, describes the impact of technology on the development team, and details summary of the significance of the entire software industry.In the level of achieving, the paper chose a branch of management information system-pharmaceutical sales management system as a software product line technology project. software under the guidance of software product line technology implemental framework, combined with the actual situation, starting from the field research, based on industry realities, through on-site needs of the collection, use case analysis, design etc. Platform steps, gives a complete management system for drug sales software system program. Finally, using java technology in struts2, spring, hibernate integration, gives a solution based on the application of this model, and gives the details the key technical points of the processing means.
