Description

<p>In this paper, a component development method is proposed for developing a business logic layer of application software. This method consists of a common architecture (PSER), basic components and a builder tool. PSER separates a business logic layer into four sub-layers; Process layer, Service layer, Entity layer and Rule layer. Then a guideline for how to extract components in a business logic layer is proposed, i.e. extracting components independently in each sub-layer. The process in each component is implemented by connecting basic components, and its connecting work can be executed visually on the builder tool. In the latter part of this paper, a case study of applying this method is shown. Especially from the perspectives of reusability of components and maintainability of application software, this method is substantiated to be effective. For example, in the case study, reuse rates of 61% and 55% in Process Layer and Service layer respectively have been achieved.</p>
