A Study of Document-based MVC Design Pattern for Improve Web-based Application System Development

Abstract

This paper proposes an improvement approach for software development, named DMVC (Document-based Model-View-Controller) design pattern. DMVC, based on XML and MVC, improve flexible on modification especially when system requirement change and software maintenance. For solving decouple and interaction problem, we add two low-level design patterns, “Abstract Factory” and “Façade”, between Model and Controller to reduce dependency. Therefore, Controller and Model can collaborate just by XML document. We also describe an application flow that is made by XML document, so the display logic of view can be adapted when workflow or requirement change. Consequently, DMVC generate an improved design pattern to assist in large application system development. To base on the XML characteristics of interoperability and human-machine readable, the benefit of DMVC is not only improving maintainability, but more decoupling Model、View、Controller components
