    Jane Crowe,

    Data persistence in entity bean means that data is live in a storage medium all the time, the medium is is the database. Live means these datas can survive even a application server crash.

    In other words the data in the database is represented in the form of java objects, which when you change it will change the underlying database.

    Hope this helps
