HOWEVER, I can give you a little bit of advice on what skills might be a little bit useful. You want to learn to create reports/data portals for something like Oracle Business Intelligence Suite, SAP's Business Objects, or IBM's Cognos.
Bank of America used to use Oracle's solutions, but as I understand it they're moving over to Business Objects. For the rest, I can't say, but there are a lot of companies that want these skills.
Any suggestions for books on it? They're training me, but the more I can learn on my own, the better.
Sorry, no suggestions for books.
Do you know if you'll be working with Crystal Reports? Or directly with the Business Objects API? Either way they're both very, very poorly designed and implemented. Good luck I hope you're getting paid well.
Want to set up a testing instance and just play around or build something? They're either not available or horribly crippled. If you can get into a company that is doing it already and you can get access, you will have an easy time learning it (but it's not exactly fun).
