Research On Electronic Government Of Municipality Based On Enterprise Architecture

The theory of Enterprise architecture proposed by Zachman is an intuitive model which represents the information infrastructure of a large organization (eg government).It provides the blueprint and framework for the current and the future information infrastructure of an organization. Federal Enterprise Architecture designed by the U.S. federal government with the Enterprise Architecture (EA) theory is the top framework of electronic government. It is the top framework of American electronic government. Federal enterprise architecture (FEA) is business-driven and data-based, abstracting application and technical architecture, introducing performance evaluation methods, providing national standards for E-government applications. Federal Enterprise Architecture Reference Model includes Performance Reference Model (PRM), Business Reference Model (BRM), Data Reference Model (DRM), Service Component Reference Model (SRM) and Technical Reference Model (TRM). FEA not only provides general standard language for architecture models, such as description business architecture, data architecture, application architecture and technical architecture, but also defines interrelation between elements of model components, meanwhile providing standards for IT project evaluation. So Federal Enterprise Architecture(FEA) is a methodology with a real integration of information technology and business and has already become a hot topic and key point of information technology.The research is based on Enterprise Architecture (EA) Theory, drawing on the experience of the U.S. Federal Enterprise Architecture (FEA), using information resource planning approach (IRP), comprehensively implements full-serviced, overall carding and analysis of government information resources in the municipal governments, builds smallest business library unit of government departments, forms Business Components of E-government enterprise architecture; sorting out information resources and information flow caused with business, builds smallest data library unit and shared subject database, forms Data Components of E-government enterprise architecture; according to the association analysis and polymerization study of the smallest business unit, forms Public Service Components of E-government enterprise architecture; Based on the business components, data components, and public service components, forms Technology Components of E-government enterprise architecture, and then forms Municipal E-government enterprise architecture(EMA), providing protection for the Intensive development of E-government.
