A SOA-Based e-Government Data Integration

Data Integration presents a core issue in the Palestinian e-Government Technical Framework. The currently used data integration model relies on the Integrated Central Database which lacks quality attributes such as: interoperability and flexibility. We purpose a SOA-based approach for data integration that achieves the above attributes. We present and analyze the current architecture and implementation of the Palestinian e-Government Integrated Central Database model. We transform the current model into a SOA framework that is realized using Enterprise Service Bus (ESB) and Web Services. The proposed framework offers database replication and connectivity functionalities for the Central Database. The proposed framework is evaluated using a scenario-based software architecture evaluation method and proves that it achieves the framework goals of quality attributes: interoperability and flexibility. Moreover, a prototype of the framework is implemented and validates the framework correctness. A specific usage is presented and further proves that the framework accomplishes its functionality and quality attributes.
