What is JPA why do we need it?

The Java Persistence API (JPA) is a specification for object-relational mapping in Java. … You can quickly switch your JPA implementation, as long as you’re not using any proprietary features. The different implementations can add additional features to innovate faster than the standard.

Is JPA still used?

There are a lot of use cases that can be better implemented with other frameworks. But in my experience, JPA and Hibernate are still a good fit for most applications because they make it very easy to implement CRUD operations. The persistence tier of most applications is not that complex.

Is JPA part of j2ee?

The Java Persistence API (JPA) is a Java specification for accessing, persisting, and managing data between Java objects / classes and a relational database. JPA was defined as part of the EJB 3.0 specification as a replacement for the EJB 2 CMP Entity Beans specification.

Should I use JPA or JDBC?

JDBC is a low level standard for interaction with databases. JPA is higher level standard for the same purpose.
