JPA @Identity Stragey values

Just to remember the strategies available in JPA for id generation. In most cases, AUTO will work fine as in

@GeneratedValue(strategy=GenerationType.AUTO)

Sometimes AUTO does not work. Use IDENTITY for a database that supports autoincement columns and SEQUENCE for a database that supports sequences. Few databases require TABLE
