PERA is a reference architecture that can model the enterprise in multiple layers and in multiple stages of the architectural life cycle. Initially PERA was part of the PERA methodology, which consisted of three main building blocks: [2] Purdue Enterprise Reference Architecture, Purdue Reference Model, and; Purdue implementation procedures manual
The resulting enterprise model (EM) represents all or part of the enterprise operation. These models will allow simulation of operational alternatives and thereby their evaluation leading. GERAM provides a generic description of all the elements recommended in enterprise engineering and integration.
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.
The Enterprise Continuum is a way of classifying solutions and architectures on a continuum that range from generic foundation architectures through to tailored organization-specific both within and outside the Architecture Repository. [19] These include architectural models, architectural patterns, architecture descriptions, and other artifacts.
Insurance claim process depicted in ArchiMate. Archimate enables modelling in different layers. ArchiMate (/ ˈ ɑːr k ɪ m eɪ t / AR-ki-mayt) is an open and independent enterprise architecture modeling language to support the description, analysis and visualization of architecture within and across business domains [1] in an unambiguous way.
The NIST Enterprise Architecture Model is a five-layered model for enterprise architecture, designed for organizing, planning, and building an integrated set of information and information technology architectures. The five layers are defined separately but are interrelated and interwoven. [2] The model defined the interrelation as follows: [3]
The basic model for the focus (or product abstraction) remains constant. The basic model of each column is uniquely defined, yet related across and down the matrix. [26] In addition, the six categories of enterprise architecture components, and the underlying interrogatives that they answer, form the columns of the Zachman Framework and these ...
These reference model can be constructed in layers, and offer a foundation for the analysis of service components, technology, data, and performance. The most familiar business reference model is the "Business Reference Model", one of five reference models of the Federal Enterprise Architecture of the US Federal Government.
