JPA 2.0

JPA 2.0 (Java Persistence API) is a set of guidelines within Java that simplifies how developers interact with databases. It allows programmers to work with objects in their code rather than writing complex database queries, making data management more intuitive. JPA 2.0 introduced features like improved query capabilities, better support for dealing with multiple data sources, and easier management of data relationships. Essentially, it streamlines the process of storing, retrieving, and managing data in Java applications, promoting cleaner code and easier maintenance.
