Bank / Accounting Unit - Business logic 
Hello guys
I'm searching for information about a bank business logic.
How does it work from the inside?

If you know something write a comment ;d. Even if you don't know anything about the topic feel free to leave a comment, any new perspective will be nice.
Thanks in advance.

Some questions: (If you have a question about the topic write it down.)
  • How does the transaction between two clients of one bank work?
    • What's all the verification process, for the transaction?
    • How and when the money is transferred from one account to other? 
  • How does the transaction process work between two clients of other banks?
    • How do they communicate?
    • How do they verify the transaction?
    • How do they trade money?
      • Is it a physic transaction or virtual?
    • When do they trade money?
If anyone would have some BPMN that are showing up business logic from inside would be great.
