I feel that the framework for integration is the programming language itself, it's Turing complete.
Getting things to glue together in the right way is a challenge though which is probably why you want it to be data driven. But inevitably you need some flexibility or logic in your data processing so you end up building an expression engine and we get into "creating a inner system/platform effect".
