  2. Multiset - Wikipedia

    en.wikipedia.org/wiki/Multiset

    The cardinality or "size" of a multiset is the sum of the multiplicities of all its elements. For example, in the multiset {a, a, b, b, b, c} the multiplicities of the members a, b, and c are respectively 2, 3, and 1, and therefore the cardinality of this multiset is 6.

  3. Interface control document - Wikipedia

    en.wikipedia.org/wiki/Interface_control_document

    An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".

  4. Data structure diagram - Wikipedia

    en.wikipedia.org/wiki/Data_structure_diagram

    A Bachman diagram is a certain type of data structure diagram, [2] and is used to design the data with a network or relational "logical" model, separating the data model from the way the data is stored in the system. The model is named after database pioneer Charles Bachman, and mostly used in computer software design.

  5. List of software architecture styles and patterns - Wikipedia

    en.wikipedia.org/wiki/List_of_software...

    Software architecture patterns operate at a higher level of abstraction than software design patterns, solving broader system-level challenges. While these patterns typically affect system-level concerns, the distinction between architectural patterns and architectural styles can sometimes be blurry.

  6. Cardinality (data modeling) - Wikipedia

    en.wikipedia.org/wiki/Cardinality_(data_modeling)

    In the object-oriented application programming paradigm, which is related to database structure design, UML class diagrams may be used for object modeling. In that case, object relationships are modeled using UML associations, and multiplicity is used on those associations to denote cardinality. Here are some examples: [5]

  7. Software design description - Wikipedia

    en.wikipedia.org/wiki/Software_Design_Description

    A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.

  8. Software design pattern - Wikipedia

    en.wikipedia.org/wiki/Software_design_pattern

    In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...

  9. Control structure diagram - Wikipedia

    en.wikipedia.org/wiki/Control_Structure_Diagram

    A control structure diagram (CSD) automatically documents the program flow within the source code and adds indentation with graphical symbols. Thereby the source code becomes visibly structured without sacrificing space.
