Object-oriented Business Processing Chain Assembly Architecture

Object-Oriented technique & Component-Oriented technique are two significant technical innovation in software engineering, both of which can improve the productivity and the quality of software development. Combining Object-Oriented technique and Component-Oriented technique, this dissertation presents a new software architecture: Object-Oriented Processing Steps Assembling Architecture(OPSAA). This architecture is specially suitable to developing enterprise information system.This architecture has the following particular properties:1. Encapsulating business information and business activities of enterprise into business objects, encouraging developers to analyze business process with Object-Oriented viewpoint.2. Supporting the individualities of business logic of enterprises. With this architecture, enterprise can inject their particular business rules into the information system.3. With Objects-pool Services, OPSAA can insure business data against illegal or inaccurate accessing, and provide a loosely coupled mechanism for its components.4. Supporting dynamic system reconfiguration.5. Supporting software reuse.Firstly, this dissertation anatomizes the structure and functions of OPSAA in detail. Then it introduces the building method and building process of Objects-poll of OPSAA.
