====== Having Spring to Create the Database Schema ======
  - Add the following in the application.properties file:<code>
spring.jpa.properties.javax.persistence.schema-generation.scripts.action=drop-and-create
spring.jpa.properties.javax.persistence.schema-generation.scripts.drop-target=drop.sql
spring.jpa.properties.javax.persistence.schema-generation.scripts.create-target=create.sql
spring.jpa.properties.javax.persistence.schema-generation.scripts.create-source=metadata
</code>
  - The create.sql, and drop.sql script will be created in the root directory. If those files have already existed, you might want to delete those first.
  - The SQL files are created based on your datasource driver.
  - Remove the above lines from the properties file afterward.
