The SAP Enterprise Architecture Framework (EAF) is a methodology and toolset by the German multinational software company SAP. It is based on The Open Group Architecture Framework (TOGAF). The TOGAF Architecture Development Method is a generic method for architecture development, which is designed to deal with most system and organizational ...
A 1996 manual of the SAP R/3 enterprise resource planning software stipulated the existence on the business reference model of the R/3 System. [9] However, in the 1990s there was a significant development of reference models in related fields, which, resulted in the developments of Integrated business planning , the Open System Environment ...
The Architecture Development Method (ADM) is applied to develop an enterprise architecture which will meet the business and information technology needs of an organization. It may be tailored to the organization's needs and is then employed to manage the execution of architecture planning activities. [18] The process is iterative and cyclic.
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
According to Forrester Research, solution architecture is one of the key components by which Enterprise Architecture delivers value to the organization. It entails artifacts such as a solution business context, a solution vision and requirements, solution options (e.g. through RFIs, RFPs or prototype development) and an agreed optimal solution with build and implementation plans ("road-map").
It supports model-driven architecture software design, and stores models using a variety of file extensions, such as .bpm, .cdm and .pdm. The internal file structure can be either XML or a compressed binary file format. It can also store models in a database repository. The PowerDesigner data modeling tool's market share in 2002 was 39%. [1]
System or Ecosystem: Modeling in general can be done at different levels of abstraction. It is useful to model the architecture of a specific application, complete with components and interactions. It is also reasonable to model the systems of applications needed to deliver a complete business process (like order-to-cash).
Fig 1. GERAM Framework: This set of components is identified in the first image and briefly described in the following. Starting from defined concepts to be used in enterprise integration (GERA), GERAM distinguishes between the methodologies for enterprise integration (GEEM) and the languages used to describe structure, contents and behaviour of the enterprise (GEML).
