Conceptual understanding of JPA

by Swati Nikam
1

In JPA, the @Entity annotation marks a class as a persistent entity.

2

@Table is used to mark a field as a column.

3

The persistence context tracks managed entities and their state across a transaction.

4

merge() deletes the entity from the persistence context.

5

JPQL queries operate on entity objects and their fields, not on database tables directly.

6

JPA is a specification for ORM in Java that defines how Java objects map to relational database tables.

7

JPQL cannot express joins between entities.
