Research And Application Of Pattern Technology On Information System Construction

Though there are many factors concerning the future of information system construction in many internal practice.no one kind of technology which is practical, effective and adaptable to Chinese enterprise or organization. Regular method such as SSA&D, RAD, Bottom-up and OOA&D not only have advantage but also shortage. It has been tested in the practice of MIS. Experiential system developer has already understand that system developer hasn' t study foregone experience. There are many problems that an important reason for this is that developer ignores this kind of experience and processing and summarizing this kind of experience and that no proper technology supports it. With appearance of pattern technology, system developer has been proceed and abstracted, so, it can be used by other people that he may not repeat it from starting, especially, that he meets some unfamiliar situation. Pattern is an important, rising and extensive techonology.Its extensive application has already bring recognition of engineering field.The paper purposes that using pattern techonogy solves the problem of construction of information system. The author who has work for five years in system developing first presents PLIS(Pattern Language For Information System) on the base of self experience and mass literature. PLIS is made of enterprise design pattern, analysis pattern and program framework pattern etc. The author presents most of patterns by example. Simultaneity, the author gets a good effect by using this pattern language in own practice.
