  2. View model - Wikipedia

    en.wikipedia.org/wiki/View_model

    A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture.

  3. 4+1 architectural view model - Wikipedia

    en.wikipedia.org/wiki/4+1_architectural_view_model

    The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.

  4. Data architecture - Wikipedia

    en.wikipedia.org/wiki/Data_architecture

    Data integration, for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems. A data architecture, in part, describes the data structures used by a business and its computer applications software .

  5. Systems architecture - Wikipedia

    en.wikipedia.org/wiki/Systems_architecture

    Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.

  6. C4 model - Wikipedia

    en.wikipedia.org/wiki/C4_model

    The C4 model is a lean graphical notation technique for modeling the architecture of software systems. [1] [2] It is based on a structural decomposition (a hierarchical tree structure) of a system into containers and components and relies on existing modelling techniques such as Unified Modeling Language (UML) or entity–relationship diagrams ...

  7. ANSI-SPARC Architecture - Wikipedia

    en.wikipedia.org/wiki/ANSI-SPARC_Architecture

    Internal Level: The internal level involves how the database is physically represented on the computer system. It describes how the data is actually stored in the database and on the computer hardware. The Three Level Architecture has the aim of enabling users to access the same data but with a personalised view of it.

  8. Three-schema approach - Wikipedia

    en.wikipedia.org/wiki/Three-schema_approach

    The notion of a three-schema model was first introduced in 1975 by the ANSI/X3/SPARC three level architecture, which determined three levels to model data. [1]The three-schema approach, or three-schema concept, in software engineering is an approach to building information systems and systems information management that originated in the 1970s.

  9. Structured systems analysis and design method - Wikipedia

    en.wikipedia.org/wiki/Structured_systems...

    By logical, we mean that the specification does not say how the system will be implemented but rather describes what the system will do. To produce the logical specification, the analyst builds the required logical models for both the data-flow diagrams (DFDs) and the Logical Data Model (LDM), consisting of the Logical Data Structure (referred ...
