JPA (Java Persistence API): A Foundation for Data Management:
Java Persistence API (JPA) stands as a stalwart in the Java ecosystem, offering a standardized approach to managing relational data. At its core, JPA provides a set of interfaces and annotations that enable developers to seamlessly interact with relational databases, abstracting away the underlying complexities. One of its primary objectives is to establish a vendor-independent way to perform CRUD operations, fostering portability across different database systems.
JPA introduces essential concepts such as entities, relationships, and queries. An entity represents a persistent data…
