Information technology architecture

Last updated

Information technology (IT) architecture is the process of development of methodical information technology specifications, models and guidelines, using a variety of information technology notations, for example Unified Modeling Language (UML), within a coherent information technology architecture framework, following formal and informal information technology solution, enterprise, and infrastructure architecture processes. These processes have been developed in the past few decades in response to the requirement for a coherent, consistent approach to delivery of information technology capabilities. They have been developed by information technology product vendors and independent consultancies, such as for example the Open Group, based on real experiences in the information technology marketplace and collaboration amongst industry stakeholders. Best practice information technology architecture encourages the use of open technology standards and global technology interoperability. Information technology architecture can also be called a high-level map or plan of the information assets in an organization, including the physical design of the building that holds the hardware.

Grady Booch, Ivar Jacobson, and James Rumbaugh are accredited with developing the first Unified Modeling Language (UML), a widely used technology modeling language.

IBM was an early developer of formal solution and infrastructure architecture methodologies for information technology.

A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real-world entities. For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner.

Software design is the process of conceptualizing how a software system will work before it is implemented or modified. Software design also refers to the direct result of the design process – the concepts of how the software will work which consists of both design documentation and undocumented concepts.

Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model Driven Architecture is a kind of domain engineering, and supports model-driven engineering of software systems. It was launched by the Object Management Group (OMG) in 2001.

A functional software architecture (FSA) is an architectural model that identifies enterprise functions, interactions and corresponding IT needs. These functions can be used as a reference by different domain experts to develop IT-systems as part of a co-operative information-driven enterprise. In this way, both software engineers and enterprise architects can create an information-driven, integrated organizational environment.

Architecture description languages (ADLs) are used in several disciplines: system engineering, software engineering, and enterprise modelling and engineering.

<span class="mw-page-title-main">Domain model</span> A model in software engineering

In software engineering, a domain model is a conceptual model of the domain that incorporates both behavior and data. In ontology engineering, a domain model is a formal representation of a knowledge domain with concepts, roles, datatypes, individuals, and rules, typically grounded in a description logic.

Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.

Unicom System Architect is an enterprise architecture tool that is used by the business and technology departments of corporations and government agencies to model their business operations and the systems, applications, and databases that support them. System Architect is used to build architectures using various frameworks including TOGAF, ArchiMate, DoDAF, MODAF, NAF and standard method notations such as sysML, UML, BPMN, and relational data modeling. System Architect is developed by UNICOM Systems, a division of UNICOM Global, a United States–based company.

The British Ministry of Defence Architecture Framework (MODAF) was an architecture framework which defined a standardised way of conducting enterprise architecture, originally developed by the UK Ministry of Defence. It has since been replaced with the NATO Architecture Framework.

<span class="mw-page-title-main">Enterprise architecture framework</span> Frame in which the architecture of a company is defined

An enterprise architecture framework defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers, or views, and offers models – typically matrices and diagrams – for documenting each view. This allows for making systemic design decisions on all the components of the system and making long-term decisions around new design requirements, sustainability, and support.

Model-driven engineering (MDE) is a software development methodology that focuses on creating and exploiting domain models, which are conceptual models of all the topics related to a specific problem. Hence, it highlights and aims at abstract representations of the knowledge and activities that govern a particular application domain, rather than the computing concepts.

The first version of the Enterprise Collaboration Architecture (ECA) has been published by the Object Management Group (OMG) in 2001. The vision of the (ECA) is to simplify the development of component based and services oriented systems by providing a modeling framework aligned with the model-driven architecture (MDA) of the Object Management Group (OMG).

Enterprise engineering is the body of knowledge, principles, and practices used to design all or part of an enterprise. An enterprise is a complex socio-technical system that comprises people, information, and technology that interact with each other and their environment in support of a common mission. One definition is: "an enterprise life-cycle oriented discipline for the identification, design, and implementation of enterprises and their continuous evolution", supported by enterprise modelling. The discipline examines each aspect of the enterprise, including business processes, information flows, material flows, and organizational structure. Enterprise engineering may focus on the design of the enterprise as a whole, or on the design and integration of certain business components.

The triune continuum paradigm is a paradigm for general system modeling published in 2002. The paradigm allows for building of rigorous conceptual frameworks employed for systems modeling in various application contexts.
