The current write up of System context diagram mistakenly assumes that context diagrams are necessarily a type of DFD. Historically, context diagrams were introduced with classic structured systems analysis, and in that form were presented as DFDs. However, context diagrams are used in other approaches, including OO models and Jackson's problem frames, where they employ different diagramming notations depending on the formalism they follow, e.g. a system object surrounded by actors or a set of interconnected problem domains.....

Is a system context diagram the same as a "context map"?

The illustration used (in the Alternatives section) seems to have come from Yellowstone (presumably the national park), whereas the content describes it as having come from the Albuquerque Police Department. This seems to be an error, but I don't have the appropriate source information to correct either one.

Would be useful to discuss what arrows represent in relationships. Is there a convention or a standard for this? — Preceding unsigned comment added by Dmjm20 ( talk • contribs) 23:58, 27 July 2020 (UTC)
@ Mdd: in this Old revision of system context diagram you mention the Albuquerque Police Department, but the relevance is unclear though the text persists to the current version. Could you provide (fittingly) some context? Arlo James Barnes 03:48, 17 February 2024 (UTC)
