What is pan data network?

Could you please elaborate on the concept of a pan data network? I've heard it mentioned in relation to cryptocurrency and finance but I'm not entirely sure what it entails. In a nutshell, could you explain what a pan data network is, how it functions, and why it's significant in the context of blockchain and digital assets? Is it a platform for data exchange, or does it serve a different purpose? Any insight you can provide would be greatly appreciated.
