2. Hatley–Pirbhai modeling - Wikipedia

   en.wikipedia.org/wiki/Hatley–Pirbhai_modeling

   A sample system context diagram using Hatley–Pirbhai modeling. Hatley–Pirbhai modeling is a system modeling technique based on the input–process–output model (IPO model), which extends the IPO model by adding user interface processing and maintenance and self-testing processing.

3. System context diagram - Wikipedia

   en.wikipedia.org/wiki/System_context_diagram

   Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram .

4. Problem frames approach - Wikipedia

   en.wikipedia.org/wiki/Problem_Frames_Approach

   The problem context contains the machine and the application domain. The machine interface is where the Machine and the application domain meet and interact. The same situation can be shown in a different kind of diagram, a context diagram, this way: The context diagram. The problem analyst's first task is to truly understand the problem.

5. IDEF0 - Wikipedia

   IDEF0 Diagram Example. IDEF0, a compound acronym ("Icam DEFinition for Function Modeling", where ICAM is an acronym for "Integrated Computer Aided Manufacturing"), is a function modeling methodology for describing manufacturing functions, which offers a functional modeling language for the analysis, development, reengineering and integration of information systems, business processes or ...

6. 4+1 architectural view model - Wikipedia

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

   4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers. The four views of the model are logical ...

7. 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 ...

8. Software design pattern - Wikipedia

   en.wikipedia.org/wiki/Software_design_pattern

   Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase ...

9. Use case diagram - Wikipedia

   en.wikipedia.org/wiki/Use_case_diagram

   A use case diagram[ 1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
