Key Terminology Flashcards
Key terms of Enterprise Architecture
Application
A deployed and operational IT system that supports business functions and services; e.g. payroll. Applications use data and are supported by multiple technology components but are distinct from technology components that support the application.
Application architecture
n applications architecture describes the behavior of applications used in a business, focused on how they interact with each other and with users. It is focused on the data consumed and produced by applications rather than their internal structure. In application portfolio management, the applications are usually mapped to business functions and to application
Description of the major logical grouping of capabilities that manage the data objects necessary to process data and support the business.
Architecture
Formal description of a system or the detailed plan of the system at component level to guide its implementation.
Structure of components their inter-relationships and the principles and guidelines governing their design and evolution over time.
Architecture continuum
Part of Enterprise continuum. Repository of architecrtural elements with increasing details and specialization. Reference modesl, strategies, building blocks .. Industry architectures and specific organization architectures
ABB Architecture Building Blocks
A building block describes a single aspect of the overall architecture model.
Architecture Development Method (ADM)
Core of TOGAF standard. Step by step approach to develop and use an enterprise architecture.
Architecture Domain
Architectural area being considered. TOGAF has 4 domains: Business, data, application and technology.
Architecture Framework
Conceptual structure used to develop, implement and sustain an architecture.
Architecture Principles
Qualitative statement of intent that should be met by the architecture. Has at least a supporting rational and a measure of importance.
Architecture Vision
A concise description of the target architecture that describes its business value and the changes to the enterprise that will result from its successful deployment. Serves as an aspirational vision and a boundary for detailed architecture development.
Baseline
Specification that has been formally reviewed and agreed upon that thereafter serves as the basis for further development or change.
Building Block
Potential reusable component of business, IT or architectural capability that can be combined with other building blocks to deliver architectures and solutions.
Can be defined at various level of detail. E.g. name or outline description or later one BB becomes multiple supporting BB and are accompanied by specifications. BB can relate to architectures or solutions.
Business Architecture
