How do I read and write from the database? Any documentation?

The main purpose for this app is simply to add and easily rearrange songs because there is no way to do that right now while on the go. Other functionality could be implemented later but my main goal is to read and write to the database

I talked to the guys at school about it and they all agree that it would be really cool however it is probably to much for us. Although, we are some of the best programmers the University has we have never had a CS job and we really dont want to get into something we dont think we can finish.

The class is called Software Engineering 2,half the class is devoted to designing and planning then the last 6 weeks is the actual developing.

Either way I want to do this for myself,for the community, and for the experience. It would be really bad ass.
