Interoperability: what is it?
Show the answer
The ability of two different systems to exchange information and use it without special effort from the user.
It plays out at four levels: technical (the channel), syntactic (the format), semantic (the meaning of the data) and organisational (who does what).
Which integration style hands another application a file dropped at a fixed time, for example every night?
- Exchanged files
- A shared database
- Service calls
- Messages in a queue

Exchanged files
A file produced by one and read by the other, without direct contact, is the simplest and oldest integration; its flaw is delay, the data being fresh only once a night.
The four levels of interoperability are: technical, …, … and organisational.

The format (JSON or CSV) is syntax; the meaning (excluding or including tax) is semantics. An exchange can succeed technically and fail on meaning.
