Java Persistence is a framework that helps developers manage data in Java applications. It allows for the storage, retrieval, and manipulation of data in a database using Java objects. This approach simplifies database interactions by allowing developers to work with familiar Java syntax instead of complex SQL queries. The most common implementation of Java Persistence is the Java Persistence API (JPA), which provides a set of guidelines for object-relational mapping (ORM). ORM enables developers to map Java classes to database tables, making it easier to manage data relationships and perform operations like creating, reading, updating, and deleting records.
