The use of UML on the use of system modeling, in the analysis and designof phase to establish a good system model, based on the model design and coding,can reduce the cost of development, indenting the development cycle, reduce development risk, so as to ensure the correct implementation of the system.Science and technology document retrieval system is a system engineering,the traditional retrieval model has been unable to adapt to the current user demand for document retrieval, the retrieval model, is proposed based on UML modeling language under B / S mode of science and technology literature retrieval system analysis and design.Along with the information technology in the information retrieval of more in-depth and wide range of application, document retrieval system has been gradually implemented in the technical maturity. To efficiently to the needs of the rapid information retrieval, we must improve information retrieval models, namely the use of more intuitive, object oriented retrieval mode, established with its own characteristics to adapt to the science and technology literature retrieval system. This paper introduces the modeling in the UML language environment analysis and design of a science and technology literature retrieval system process. Create a set of effective programs. This paper introduces the literature retrieval system analysis, including feasibility欢迎下载精品学习资源analysis, business process analysis； system design part mainly introduced thesystem function design and based on UML modelThe paper mainly introduced this topic development background, systemanalysis, system design, system model for the analysis and design of database.Keywords: Science and technology literature； retrieval system； UML； database欢迎下载精品学习资源目录摘要 ......................................................................
