A Study of E-Government Architectures

摘要

The success of an e-government initiative depends on different factors such as economic strategies, countries political and decisions initiatives, countries readiness to citizen connectivity, etc. We concentrate in this paper on architectural design of e-government systems according to a software engineering point of view which among all other considerations promises also the success of the final operational platform. In fact, architectural design is a key factor for a success of any system. The purpose of this paper is to study and analyze existing (software) architectures of e-government systems in order to have a better vision of the architecture underlying and characterizing an EGP (E-Government Platform). This is fundamental before proposing our own architecture, particularly for a federated project of research S2EG1,conducted in the context of Tunisia country e-government initiative. In this presented work, we particularly want to highlight architectural design principles, the high level components that constitute the architecture, specifically the software components and the used technology.
