====Models====

**Models** are sets of [[data points|data points]] that translate one or more [[input|inputs]] and [[constant|constants]] into [[output|outputs]] and [[calc|calculations]].

Complex systems - those with several distinct pieces - will often be broken up into several smaller models. This is because it's much easier to develop, test, debug and sign-off on individual pieces of the system than it is to try and build the entire thing at once.

Models can communicate with one-another - the outputs of one model can feed in as the inputs to another.
