The video tutorial discusses the use of JPA and Hibernate annotations, focusing on the flexibility of JPA in switching between persistence providers. It explains the @Table annotation, which is used to define table names in databases, and highlights the importance of naming conventions. The tutorial also covers how to map entities to tables using JPA, ensuring that queries are correctly directed to the appropriate tables. Finally, it demonstrates how to revert changes and concludes with a summary of key points.

What is one advantage of using JPA over Hibernate-specific features?

• JPA requires less configuration than Hibernate.

• JPA is more secure than Hibernate.

• JPA provides better performance than Hibernate.

• JPA allows for easier switching between different persistence providers.

What is the primary purpose of the @Table annotation in JPA?

• To define the primary key of a table.

• To specify the database schema.

• To map an entity to a specific table name.

• To configure caching for an entity.

How does JPA handle differences between entity and table names?

• It requires manual configuration for each query.

• It automatically maps the entity to the table using the @Table annotation.

• It does not support different entity and table names.

• It uses a default naming convention that cannot be changed.

What happens if the @Table annotation is removed from an entity?

• The entity will be mapped to a default table named 'default_table'.

• The application will fail to start.

• The entity will be mapped to a table with the same name as the entity.

• The entity will not be mapped to any table.

What is a common convention when naming tables in databases?

• Using underscores to separate words in table names.

• Using hyphens to separate words in table names.

• Using spaces to separate words in table names.

• Using camelCase for table names.
