ORM stands for Object-Relational Mapping (ORM) is a programming technique for converting data between relational databases and object oriented programming languages such as Java, C# etc.
An ORM system has following advantages over plain JDBC S.N.
Advantages
1 Lets business code access objects rather than DB tables.
2 Hides details of SQL queries from OO logic.
3 Based on JDBC 'under the hood'
4 No need to deal with the database implementation.
5 Entities based on business concepts rather than database structure.
6 Transaction management and automatic key generation.
7 Fast development of application.
