Reusable Pattern And Its Code Packaging Technology For Business Component

In large scale software for enterprise, business component is reused to adapt requirement changes by parameterization and configuration in large scale software for enterprise, but it is difficulty to develop because of the large granularity, various parameters and complexity of the structure. The business component is the software implementation of the processing business object, such as enterprise bills. With data information and related professional activity included, the business component is a business semantics integrated and large granularity component. The development of the large granularity soft component takes much repeat work and the components'ponderous code frustrates its quick refectory.This paper presents reusable pattern and its code packaging technology for the business component to improve the efficiency and correctness of development and in a certain degree resolve the balance of component granularity. So it largely decreases the labor cost for business component development, makes for reuse of business component and enhances the ability of quick refactoring.This paper starts from business component of enterprise applications systems, mainly studied the concept, characteristics, model, reuse characteristics of business component and the relationship between business components.According to all above, the typical reusable patterns are abstracted from the existing component:data correlation pattern, user interface pattern and authority configuration pattern. This paper proposed analysis, designing and realizing process of these patterns in detail.Finally, base on Ices platform of research center on Intelligent Computing for Enterprise & Services in Harbin Institute of Technology at Wei Hai for R & D platform, reusable models and code packaging are implemented. Meanwhile, the feasibility and effectiveness of the reuse rate of business component get a good validation.
