The Research And Applications On Domain-specific Software Architecture

Software architecture (SA) is emerging as one of the primary research areas in software engineering recently and one of the key technologies to the development of large-scale software-intensive system. Software reuse is a goal pursued by software engineering community chronically. A recent method addressing it is DSSA (Domain-specific Software Architecture).It analyzes the pertinent domain, captures the typical requirements and designs corresponding reference software architecture to satisfy those requirements.Along with the development of securities business in Taiwan, nowadays credit transaction and delivery system for the need of securities on loan system. It can't meet the market demand. To tie in with the development of the securities market, it is necessary to establish of a more complete system of securities on loan system. So, this dissertation is about oriented securities on loan system that is based on the Taiwan's securities market.This dissertation firstly introduces the concept of software architecture, DSSA and domain engineering. Based the feasibility of domain engineering, it analyzes and set up engineering modeling in the field of securities on loan. It set up a simple application framework through the analysis of traditional business processes. At the same time, it is extracted of a universal framework from the framework. For example, core business processes and accessory business processes. It include maintenance table(create, update, delete) and data transmission in core business processes. In order to meet the user need, it support business processing logic, such as query page, create page, update page, delete page and so on. It is using the design of hierarchical structure system to divide into UI layer, Business Facade layer, Business Logic layer, Data Access layer and the public layer, and combined with the MVC architecture model, separating business layer and data layer, low coupling. Finally, it rely on the platform which provide OM functional properties, such as rapid development, and simplified operation, high security, and modular features, etc., the realization of securities on loan system for integrated development.
