  2. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    The so-called zero level is followed by DFD 0, starting with process numbering (e.g. process 1, process 2). In the next, the so-called first levelDFD 1—the numbering continues For example, process 1 is divided into the first three levels of the DFD, which are numbered 1.1, 1.2, and 1.3. Similarly, processes in the second level (DFD 2) are ...

    en.wikipedia.org/wiki/Data-flow_analysis

    Data-flow analysis is a technique for gathering information about the possible set of values calculated at various points in a computer program.A program's control-flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate.

    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 ...

    en.wikipedia.org/wiki/Structured_Analysis_and...

    Structured analysis and design technique (SADT) is a diagrammatic notation designed specifically to help people describe and understand systems. [1] It offers building blocks to represent entities and activities, and a variety of arrows to relate boxes. These boxes and arrows have an associated informal semantics. [2]

    Where necessary, the option will be documented with a logical data structure and a level 1 data-flow diagram. The users and analyst together choose a single business option. This may be one of the ones already defined or may be a synthesis of different aspects of the existing options.

  8. IDEF3 - Wikipedia

    en.wikipedia.org/wiki/IDEF3

    One of the primary mechanisms used for descriptions of the world is relating a story in terms of an ordered sequence of events or activities. The IDEF3 Process Description Capture Method was created to capture descriptions of sequences of activities, which is considered the common mechanisms to describe a situation or process.

  9. Warnier/Orr diagram - Wikipedia

    en.wikipedia.org/wiki/Warnier/Orr_diagram

    Each process is defined in a hierarchical manner i.e. it consists of sets of subprocesses, that define it. At each level, the process is shown in bracket that groups its components. Since a process can have many different subprocesses, Warnier/Orr diagram uses a set of brackets to show each level of the system.
