A SOA Based Framework for the Palestinian e-Government Integrated Central Database

Abstract

The Integrated Central Database is one of the core components in the Palestinian e-Government Technical Framework. The current Integrated Central Database model lacks features such as: Interoperability, Flexibility, and Manageability. The purpose of this research is to propose a SOA based solution for the Central Database that achieves the above features. This research presents and analyses the current architecture and implementation of the Palestinian e-Government Central Database model. The research proposes changing the current model into a Service Oriented Architecture (SOA) framework that is realized using Enterprise Service Bus (ESB) and Web Services. The proposed framework offers database replication and connectivity functionalities for central database. The proposed framework is evaluated by using a scenario based software architecture evaluation method and proves that it achieves the quality attributes set as goals for the framework which are: Interoperability, Flexibility and Manageability. Moreover, a prototype of the framework is implemented and validates the framework correctness. A specific usage scenario for the framework is discussed and further proves that the framework accomplishes its functionality and quality attributes.
