Before running the project, go to the MySQL Workbench app, the cha6_dbtest table, and cha6_dbtest_schema. There you will notice that there will be no table named user_jpa, which was mentioned in the UserModel class as a table name. 

Here is the screenshot of the schema where we have no table:

Let's run the application, check the database again, and refresh the schema. Notice that now there is a table as we mentioned in the @Table annotation of the UserModel. This has all the columns of that object, including—id, name, email, and contact_number.

Here is the screenshot of the updated database:

The testing system is the same as the JDBC. Please check this yourself, and if you are confused, then go to the Testing the Output of JDBC project.
