The Zachman Framework of enterprise architecture. The Zachman Framework is an enterprise ontology and is a fundamental structure for enterprise architecture which provides a formal and structured way of viewing and defining an enterprise. The ontology is a two dimensional classification schema that reflects the intersection between two ...
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.
Examples include the "4+1" view model, the Zachman Framework, TOGAF, DoDAF and, of course, RM-ODP. A viewpoint is a subdivision of the specification of a complete system, established to bring together those particular pieces of information relevant to some particular area of concern during the analysis or design of the system.
The Zachman Framework provides the broad context for the description of the architecture layers, while EAP focuses on planning and managing the process of establishing the business alignment of the architectures. [2] EAP is planning that focuses on the development of matrixes for comparing and analyzing data, applications, and technology.
The first use of the term "enterprise architecture" is often incorrectly attributed to John Zachman's 1987 A framework for information systems architecture. [12] The first publication to use it was instead a National Institute of Standards (NIST) Special Publication [13] on the challenges of information system integration.
The TEAF Matrix of Views and Perspectives.. A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture.
As shown in the figure, the FEAF partitions a given architecture into business, data, applications, and technology architectures. The FEAF overall framework created at that time (see image) includes the first three columns of the Zachman Framework and the Spewak's Enterprise Architecture Planning methodology. [3]
In a way the NIST Enterprise Architecture Model was ahead of his time. According to Zachman (1993) in the 1980s the "architecture" was acknowledged as a topic of interest, but there was still little consolidated theory concerning this concept. [19] Software architecture, for example. become an important topic not until the second half of the ...
