SOLVING DESIGN ISSUES IN WEB META-MODEL APPROACH TO SUPPORT END-USER DEVELOPMENT
Buddhima De Silva, Athula Ginige · 2007
End-user development is proposed as a solution to the issues business organisations face when developing web applications to support their business processes. We are proposing a meta-model based development approach to support End-User Development. End-users can actively participate in web application development using tools to populate and instantiate the meta-model. The meta-model has three abstraction levels: Shell, Application and Function. At Shell Level, we model aspects common to all business web applications such as navigation and access control. At Application Level, we model aspects common to specific web applications such as workflows. At Function Level, we model requirements specific to the identified use cases. In this paper we discuss how we have solved the issues in application development for business end-users such as need for central repository of data, common log in, optimizing user model, application portability and balance between “Do it Yourself” (DIY) and professional developers in hierarchical meta-model approach. These solutions are being incorporated into Component based EApplication Development and Deployment Shell (CBEADS) version 4, supporting meta-model implementation. We believe that these solutions will help end-users to efficiently and effectively develop web applications using meta-model based development approach.
