Generalised Enterprise Reference Architecture and Methodology (GERAM) is a generalised Enterprise Architecture framework for enterprise integration and business process engineering. It identifies the set of components recommended for use in enterprise engineering.〔J.G. Nell, NIST (1997). "(An Overview of GERAM )" ICEIMT'97 International Conference on Enterprise Integration Modelling Technology 1997. Updated 30 January 1997〕 This framework is developed in the 1990s by an IFAC/IFIP Task Force on Architectures for Enterprise Integration. The development started with the evaluation of then existing frameworks for enterprise integration, which was developed into an overall definition of a so-called "generalised architecture", which was named GERAM for "Generalised Enterprise Reference Architecture and Methodology".〔P. Bernus, and L. Nemes (1994). "A Framework to Define a Generic Enterprise Reference Architecture and Methodology". In: ''Proceedings of the International Conference on Automation, Robotics and Computer Vision (ICARCV'94)'', Singapore, November 10–12, 1994.〕 == Overview == One of the basics of GERAM is that enterprise modelling was seen as the major issue in enterprise engineering and integration. It contained several of building blocks, in which the methodologies and the corresponding languages have been implemented, such as: * Enterprise modelling tools (GEMT) to support the enterprise integration process. * Ontological theories (OT), * Generic enterprise models (GEMs) and * Generic modules (GMs) The building blocks where designed to support the modelling process by providing means for more efficient modelling.〔 The modelling process will result in an enterprise model (EM) which represents all or part of the enterprise operation. These models will allow simulation of operational alternatives and thereby their evaluation leading to the optimum structure, contents and behaviour of the enterprise operation. GERAM provides a generic description of all the elements recommended in enterprise engineering and integration. Generalised Enterprise Reference Architecture and Methodology (GERAM) is an enterprise-reference architecture that models the whole life history of an enterprise integration project from its initial concept in the eyes of the entrepreneurs who initially developed it, through its definition, functional design or specification, detailed design, physical implementation or construction, and finally operation to obsolescence. The architecture aims to be a relatively simple framework upon which all the functions and activities involved in the aforementioned phases of the life of the enterprise-integration project can be mapped. It also will permit the tools used by the investigators or practitioners at each phase to be indicated. The architecture defined will apply to projects, products, and processes; as well as to enterprises.〔 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「Generalised Enterprise Reference Architecture and Methodology」の詳細全文を読む スポンサード リンク
