When talking about electronic drawings is it correct to use scheme or should I only use schematic?

    I would use schematic. Schema to me is a database overview or XML description - scheme is something else – mplungjan Jul 31 '13 at 9:24
  • @mplungjan Do you mean schema (when talking about DB)? – moonstar Jul 31 '13 at 9:26
  • Yes, you are correct. And Scheme does not sound right either – mplungjan Jul 31 '13 at 9:27

    In general, "scheme" means "plan", but not "plan" in the sense of a "blueprint." – oosterwal Aug 1 '13 at 0:47

Schema

  • entity relationship diagrams (ERD) used to visually represent a database or data warehouse
  • XML or similar non-physical descriptions

Schematic

  • physical electronic circuitry diagrams
  • diagram of a physical assembly, with a variety of formats e.g. exploded

Blueprint

  • layout for a physical structure

Scheme

  • British English: An investment plan or public policy action. There is no pejorative connotation.
  • American English: A clever plan of action, possibly unethical or even illegal. There is a definite pejorative connotation.

For electronic drawings, schematic is the proper word choice. Do not use schema. Do not use scheme, especially not if intended for American English.
