The Singapore Government Enterprise Architecture (SGEA) programme was established to support and enable the business strategies, objectives, and a vision of a 'Networked Government'. It adopted a federated architecture approach similar to the United States government. SGEA is a set of blueprints comprising the Business Architecture (BA), Information Architecture (IA), Solution Architecture (SA) and Technical Architecture (TA) of the Singapore Government. It provides a holistic view of business functions, common data standards, and shared ICT systems and infrastructure. This programme facilitates the identification of opportunities for collaboration among agencies, encouraging greater sharing of data, systems and processes across agencies. ==Reference Models== The SGEA has four developed reference models which are listed below: * Business Reference Model (BRM) - The BRM addresses the BA, and describes the Lines of Businesses and Business Functions performed by different government agencies. * Data Reference Model (DRM) - The DRM addresses the IA. It specifies the data definitions for data elements that are commonly used across government. * Solution Reference Model (SRM) - The SRM addresses the SA, and describes the systems and service components that can be shared across government. * Technical Reference Model (TRM) - The TRM is addressed by the Service-wide Technical Architecture (SWTA) established since 2002. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Singapore Government Enterprise Architecture」の詳細全文を読む スポンサード リンク
