an enterprise-wide architecture that captures common architectural decisions that are common and enforced across all applications and data centers within an enterprise.
An organization's framework of technology hardware, software and related policies.
A high level enterprise wide data warehouse framework that describes the subject areas, sources, business dimensions, metrics, business rules and semantics of an organization. It is used to identify shared sources, dimensions, metrics and semantics in an iterative data mart or iterative subject area development methodology. ()

a definition of the IT objectives as they fulfill the business strategy of the organization
a description of the goals of an organization, how these goals are realized by business processes, and how these business processes can be better served through technology

A strategic resource that aligns business and technology, leverages shared assets, builds internal and external partnerships, and optimizes the value of information technology services.
The model of organisation and operation for a Public Administration, as described in a set of interrelated views. It consists of the generic model and its various instances that may vary e.g. amongst the particular Public Administrations in which the Enterprise Architecture is employed.
The framework that defines the overall structure of the business and the human technical and information infrastructure that supports the business: based on defined business needs and principles that guide implementation choices.
A structure that describes the organization's business activities, the applications and automation that support them, the information necessary to carry them out, and the technologies and infrastructure used to deliver the applications and information. It provides a strategic basis for implementing IT in a way that takes best advantage of available IT technologies. It also helps organizations to extend and evolve IT capabilities in response to changing needs of the business environment. Technical advantages that result from an effective EA provide important business benefits.
A means for describing business structures and processes that connect business structures.
The explicit description and documentation of the current and desired relationships among business and management processes and information technology. (OMB Circular A-130, Management of Federal Information Resources, 8 February 1996)
An Enterprise Architecture (EA) establishes an agency-wide roadmap to achieve an agency's mission through optimal performance of its core business processes within an efficient IT environment. An EA is made up of four components: Business Architecture, Applications Architecture, Data Architecture, and Technical Architecture.
Enterprise architecture is a comprehensive framework used to manage and align an organization's business processes, information technology (IT) software and hardware, local and wide area networks, people, operations and projects with the organization's overall strategy.
A structure that describes: The organization's business activities. The applications and automation that support those business activities. The information necessary to carry out those business activities. The technologies and infrastructure used to deliver the applications and information. The enterprise architecture is the blueprint for integrating these key business processes and technologies.
Enterprise Architecture is a top-down, business strategic-driven process that coordinates the parallel, internally consistent development of enterprise business, information, and technology architectures, as well as the enterprise application portfolio. It represents the holistic expression of the enterprise's key program, information, application, and technology strategies and their impact on program functions and processes. Conducted within an appropriate, collaborative organization/governance context, EA artifacts consist of a common requirements vision (CRV) and conceptual architecture (CA), as well as current- and future-state models of four key components: Enterprise Business Architecture (EBA), Enterprise Information Architecture (EIA), Enterprise Technical Architecture (ETA), and Enterprise Application Portfolio (EAP).
A comprehensive approach used to manage and coordinate an agency’s business processes and information systems so that they align with the agency’s core goals and strategic direction.
Enterprise architecture is the practice of applying a comprehensive and rigorous method for describing a current and/or future structure and behavior for an organization's processes, information systems, personnel and organizational sub-units, so that they align with the organization's core goals and strategic direction. Although often associated strictly with information technology, it relates more broadly to the practice of business optimization in that it addresses business architecture, performance management, organizational structure and process architecture as well.
