An Electronic Government Integrated System Using Service Oriented Architecture
The aim of the study was to investigate the application of Service Oriented Architecture (SOA) as an integration solution to disparate departmental government information systems with the aim of improving service delivery. The specific objectives that the study addressed include identification of business work flows, communication flows, and the common information requirements within the three departments of the Ministry of Immigration and Registrar of Persons; IMD, CRD and NRB; identification of the current and potential integration difficulties of the three systems; development of a SOA model of the proposed integration solution; building a system prototype using JAVA SOAP web services to implement the model; testing, evaluation and validation of the prototype. The data collection involved interviewing staff at the ministry department and carefully documenting all the processes. The findings of the study revealed that service delivery can be significantly improved by the adoption of Service Oriented technology. These findings have multiple implications on service delivery and also lowering of costs related to system development.
