[ 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 .
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.

[ 2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
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.
Structured systems analysis and design method. Structured systems analysis and design method ( SSADM) is a systems approach to the analysis and design of information systems. SSADM was produced for the Central Computer and Telecommunications Agency, a UK government office concerned with the use of technology in government, from 1980 onwards.
Information flow diagram. An information flow diagram ( IFD) is a diagram that shows how information is communicated (or "flows") from a source to a receiver or target (e.g. A→C), through some medium. [ 1]: 36–39 The medium acts as a bridge, a means of transmitting the information. Examples of media include word of mouth, radio, email, etc.
