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.
Advantage of ORM:
ORM removes dependencies on Database.
Because JDBC code is dependent upon the Database software being using. i.e. Our persistence logic is dependent because of using JDBC. Here we are inserting a record into Employee table but our query is Database software dependent i.e. here we are using MySQL. But if we change our Database then this query will not work.
An ORM tool simplifies the data creation, data manipulation and data access. It is a programming technique that maps the object to the data stored in the database.
