Hello, I am trying to find where exactly ips stores user and transaction data. I was looking through some of the files and couldn't seem to find anything. Thanks.

What kind of user and transaction data?

Most user data is stored in the core_members database table, but some data may be located elsewhere.

Most Commerce payment transaction data is stored in nexus_transactions, but I'm not confident that's the transaction data you are inquiring about.

I ended up figuring it out thanks anyways!
