Research On Analysis Patterns In Information System Analyses

Software Reuse is the incessant quarry of people engaged in software trade and it can improve software productivity and software quality. During the process of analyzing software systems people can often find that the analysis models in different fields have a lot of resemblances, and this makes people pay attention to the reuse of analysis models. Analysis pattern is the technique used to solve the reuse of analysis models in Object-Orient system.Analysis patterns are reusable 00 models. Analysis patterns are a suit of conception which doesn't reflect the realization of real software but reflect the universal structure of business model. Analysis patterns mostly come from specific fields, but they usually can also be used in other fields.Nevertheless people encounter some problems during the course of using analysis patterns, and this is primary because of scarcity of methodology guidance. This thesis researches deeply into analysis patterns, aiming at the problems of analysis patterns appliance, according to of the characteristic and effect of analysis patterns, consulting the research of inland and outland, summarizes an analysis patterns appliance method model which integrates analysis patterns and the UML analysis method. The method model has four facets: model-creating language, process model, appliance principle, and analysis pattern extract This thesis also researches the background, idea, purpose and effect of five analysis model: Separation of Knowledge-level and Operation-level, Quantity, Observation, Stock Manager and Account, and bring forward a new analysis pattern: Stock Manage- Analyzer. At last this thesis analyzes the Inventory Subsystem of the Electric Material Management Information System under the guidance of the method model, creating analysis model and validating the reusity of analysis patterns and the validity of the method model.Through the research of the method of analysis patterns appliance, this thesis provides the guidance of using analysis pattern effectively in 00 analysis and realizing analysis model reuse, and partly solves the problems of analysis patterns appliance.
