I do fraud investigations for a bank. We spend an insane amount on labor costs because all of our transactional data resides in different systems. Want to review credit card data? Go pull system X. Want to review wire transfers? Go pull system Y. Etc etc. some of these things have to be separated out of necessity (e.g. card data is stored in a particular way due to regulations), but I would easily pay 10k / y to be able to get a complete view of customer transaction activity from a single place. We'd save millions in labor costs if someone could pull it off correctly.
