This is a fundemental concept of EJBs. This means that whenever EJBs change fields and rows in database tables, all changes are either "committed" to the database or all changes are "rolledback". Commits and rollbacks are synchronized with the start and end of an EJB method execution. Also, when defining methods in EJBs, you can declare how you want your transactions to be managed.
This is only the tip of the iceberg but I hope this helps.
