What standards does Java Persistence API (JPA) conform to?

Java Persistence API (JPA) corresponds to the Java EE (Enterprise Edition) standard, and more precisely, it is part of the Jakarta EE (formerly Java EE) specification. JPA defines a standard interface for managing data persistence in Java applications, providing object-relational mapping (ORM).

Main standards and specifications associated with JPA:

• Java EE / Jakarta EE — JPA is part of the platform.
• ORM (Object-Relational Mapping) — JPA standardizes ORM in Java.
• JPA is based on the EJB 3.0 (Enterprise JavaBeans) specification, which introduced a standard for persistence.

Thus, JPA is a standard API for working with databases in Java, ensuring portability and compatibility across different ORM implementations.
