Database in Phonegap Blackberry

I am new to phonegap - blackberry. I am using Apache ANT, BBWP. I want to connect the database. I refer http://docs.phonegap.com/phonegap_storage_storage.md.html but i cant understand fully. Can any one send me step by step to connect database and its operations. I have some more doubts, How to access access phone music player, and how to read read phone memory / SD ca开发者_Go百科rd.

Thanks in advance.

As far as I can see, this storage tutorial is about creating your own SQLLite like database. To connect to an existing database on a server, web services with JSON would be a way.
