2. Data-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Data-flow_diagram

   A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops. Specific operations based on the ...

3. Data model - Wikipedia

   en.wikipedia.org/wiki/Data_model

   Data-Flow Diagram example [19] A data-flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data-flow diagram can also be used for the visualization of data processing (structured design).

4. Data-flow analysis - Wikipedia

   en.wikipedia.org/wiki/Data-flow_analysis

   A canonical example of a data-flow analysis is reaching definitions. A simple way to perform data-flow analysis of programs is to set up data-flow equations for each node of the control-flow graph and solve them by repeatedly calculating the output from the input locally at each node until the whole system stabilizes, i.e., it reaches a fixpoint.

5. Dataflow - Wikipedia

   en.wikipedia.org/wiki/Dataflow

   There have been multiple data-flow/stream processing languages of various forms (see Stream processing). Data-flow hardware (see Dataflow architecture) is an alternative to the classic von Neumann architecture. The most obvious example of data-flow programming is the subset known as reactive programming with spreadsheets. As a user enters new ...

6. Dataflow programming - Wikipedia

   en.wikipedia.org/wiki/Dataflow_programming

   Dataflow programming. In computer programming, dataflow programming is a programming paradigm that models a program as a directed graph of the data flowing between operations, thus implementing dataflow principles and architecture. [1] Dataflow programming languages share some features of functional languages, and were generally developed in ...

7. Structured analysis - Wikipedia

   en.wikipedia.org/wiki/Structured_analysis

   Structured analysis consists of interpreting the system concept (or real world situations) into data and control terminology represented by data flow diagrams. The flow of data and control from bubble to the data store to bubble can be difficult to track and the number of bubbles can increase. One approach is to first define events from the ...

8. Flowchart - Wikipedia

   en.wikipedia.org/wiki/Flowchart

   A simple flowchart representing a process for dealing with a non-functioning lamp. A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their ...

9. Function model - Wikipedia

   en.wikipedia.org/wiki/Function_model

   Flow: Movement of data or material in the process. External Entity: External to the modeled system, but interacts with it. Now, with these symbols, a process can be represented as a network of these symbols. This decomposed process is a DFD, data flow diagram. Example of functional decomposition in a systems analysis.
