Question

What is the first step in the Hibernate communication process with the RDBMS?

A) Mapping the Java objects to database tables
B) Establishing a database connection
C) Writing SQL queries
D) Inserting data into the database

Answer 1

The first step in the Hibernate communication process with the RDBMS is establishing a database connection. Once the connection is established, Hibernate proceeds to map the Java objects to database tables. After the mapping is done, Hibernate can execute SQL queries to interact with the RDBMS and perform operations.

Step-by-step explanation:

The first step in the Hibernate communication process with the RDBMS is establishing a database connection. This is essential in order to interact with the relational database and perform database operations.

Once the connection is established, Hibernate then proceeds to map the Java objects to database tables. This involves defining the object-relational mapping (ORM) configurations that specify how the objects are to be stored in the database tables.

After the mapping is done, Hibernate can then execute SQL queries to interact with the RDBMS and perform operations such as retrieving, updating, or deleting data.
