For The Business Framework In The Field Of Special Components Library Research And Practice

Software reuse can effectively solve the software crisis,enhance efficiency and quality of software development,reduce the development and the maintenance cost. Component Based Software Development method is one practice method which software reuse,component technology is the core technology which supports software reuse.In order to reuse component,we must unceasingly carry on the component accumulation before those may reuse,and organize them in repository. Applying the component technology to the development of domain software can reuse more resources,reuse higher level and bigger granularity reusable resources. The reuse key is the domain framework.Reuse usually includes the framework design,framework based the component description,retrieval,assembly and building system.Under situation that the components are very great and relations between them are quite complex,how to carry on component retrieval based framework highly effective in repository becomes one very important question.We must consider how to organize the repository structure,to enable the component accurately to be described,to maintain the higher retrieval and reuse efficiency.This article will perform based on the framework and the component development method to improve,proposes component based framework development method.In order to make component retrieval and reuse based on the specific framework more convenient,this article proposes to construct Framework Oriented Special Repository(FOSR),based on the distributed,universal repository. FOSR mainly solves two problems:firstly,organizes the distributed,isomerous and universal repository information with the unification description model,and manages the specific framework component information centralized.Secondly,enhances framework oriented component retrieval efficiency,realizes the component relative retrieves and component relative selection.This article introduced architecture of FOSR,discussed the description and classified method of universal repository.FOSR classifies the component with the multi-dimensional method.This article constructs component description ontology in FOSR,enable the distributed component to have one unified description model in FOSR,elimination component description and retrieval semantic isomerism question, simultaneously constructs relative retrieval strategy collection in FOSR,and supports the retrieval extension based on the strategy collection and component ontology, realizes the component relative retrieves and selection,caused to component based framework reuse conveniently.
