Research And Application Of Design Patterns Development In Mis

Design patterns is a particular scene of a constantly recurring problem of the solution, which contains the experience of the design of systems development experience. With the application of information technology increasingly widespread, management information systems in existing applications software development is a large proportion, although their needs vary, but in the design development process there are many similarities.So if we can find and extract the similarities, and to design such a good idea to apply the design, it will no doubt greatly enhance the development and maintenance of the efficiency and quality. At the same time, based on the model of the design can also speed up the design efficiency, and increase development team productivity and software quality.This thesis summarized the design patterns and object-oriented principles, and analyzed the existing problems in current management information system development.Theis mainly research the duplication and coding structure and excessive fluctuations caused by the adverse effects on design. Conducted in-depth study and application of research findings to the of Shandong University of Science and Technology integrated management information system development process, to resolve the actual system in the development of the large number of repeat coding problems and fluctuations in effect.This thesis mainly researches on the relevance of the design patterns,and put forward the way of improvement to traditional factory method pattern.The traditional factory method pattern needs only one instance.When creating the product through ,it will always check that whether there is factory existed.This check process must reduce the efficiency of software running.So this thesis take singleton pattern into factory method pattern to guarantee there is only one instance existed.After improvement,this thesis takes it into use and get a good result.This thesis takes template pattern to implement the builder pattern and through the database operation validates the pattern conversion.And then analysed the advantages and disadvantages after conversion.At last,this thesis through using the strategy pattern and brige pattern solved the frequent problem in MIS—Class Blast.
