Java Persistence API

The Java Persistence API (JPA) is a specification in Java that simplifies how developers manage data in applications. It provides a standard way to store, retrieve, and manipulate data in databases using Object-Relational Mapping (ORM). This means that developers can work with data as Java objects rather than complex SQL queries. JPA helps improve productivity and maintainability by offering a consistent approach to interact with databases, allowing applications to be more flexible and easier to change over time. It's widely used in Java applications to handle data effectively.
