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.
Lightweight Presentation Protocol (LPP) is a protocol used to provide ISO presentation services on top of TCP/IP based protocol stacks. It is defined in RFC 1085. The Lightweight Presentation Protocol describes an approach for providing "streamlined" support of OSI model-conforming application services on top of TCP/IP-based network for some constrained environments.
Information technology architecture The term Information Technology Architecture, with respect to an executive agency, means an integrated framework for evolving or maintaining existing information technology and acquiring new information technology to achieve the agency’s strategic goals and information resources management goals.
These concepts were also developed by Dietz and others into a framework for enterprise architecture, entitled Architecture Framework (XAF). [9] In the new millennium the French company Sogeti developed a methodology based on the DEMO, called Pronto. The further development of DEMO is supported by the international Enterprise Engineering ...
Structure of the TOGAF Architecture Development Method (ADM). [1] The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 [2] that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. [3] TOGAF is a high-level approach ...
Enterprise modelling is the process of building models of whole or part of an enterprise with process models, data models, resource models and/or new ontologies etc. It is based on knowledge about the enterprise, previous models and/or reference models as well as domain ontologies using model representation languages. [3]
These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition. Contrasting the functional modeling, another type of systems modeling is architectural modeling which uses the systems architecture to conceptually model the structure, behavior, and more views of a system.
ARCADIA, a model-based engineering method for systems, hardware and software architectural design. ARCADIA ( Arc hitecture A nalysis & D esign I ntegrated A pproach) is a system and software architecture engineering method based on architecture-centric and model-driven engineering activities.
