TOGAF Standard Definitions (38 cards)
Abstraction
Providing generalised of specific descriptions of complex content - relevant issues being identified of complex architectures before detail is attempted
Actor
Person or structure with many roles, interacts with activities
Application Architecture & App Component
structural descriptions of applications that have key capabilities and manage data assets - application is an encapsulation of application functionality > bhvr, data, provides a services (available through interfaces). application maintains a dta components and is enabled by technology
Application Service
a behaviour request-able from an application, delivers one or more business services
Architectural style
features of a context in which architecture is performed, principles, characteristics that steer how architecture is performend

Architecture Framework
Conceptual structure to manage an architecture
Architecture Governance
Monitoring practice to direct architecture-work - delivering outcomes and adhere to principles & standards
Architecture Landscape & Levels

Architecture Partition
Subset of an architecture used to facilitate its development & management (Agile TOGAF).
Architecture Principles

Architecture VIEW vs VIEWPOINT
A view is a representation of a system from a specific perspective. A viewpoint is a convention or schema for an architecture view (i.e. ArchiMate Viewpoints)
Architecture Visio
Description of Target architecture including business value and changes from a good deployment = it is our aspiration that sets the boundaries for the architecture development
Artifact
a work product describing an aspect of the architecture i.e. diagrams or catalogues
Baseline
formally reviewed specification and basis for further development. should be changed through change control procedures
Boundaryless Information Flow
Access to information to support business process improvements
Building Block > Architectural Building Block
A re-usable component, when combined with others it delivers architectures and solutions (Name or Description) – Architectural components specifying Solution Building blocks at a logical level (not specific)
