An example of an AI chatbot conversation about Java Persistence API and its usage in Java applications.
What is the Java Persistence API?
The Java Persistence API (JPA) is a specification for accessing, persisting, and managing data between Java objects and a relational database.
How does JPA differ from JDBC?
JPA is an abstraction over JDBC, providing a more object-oriented approach to database interactions, while JDBC is a lower-level API.
Can you explain the concept of Entity in JPA?
In JPA, an Entity represents a table in a database, and each instance of an Entity corresponds to a row in that table.
What are some common annotations used in JPA?
Common JPA annotations include @Entity, @Table, @Id, @GeneratedValue, and @Column, which define the mapping between Java classes and database tables.
