Query Language (JPQL)

Java Persistence Query Language (JPQL) is a specialized language used to interact with databases in Java applications. It allows developers to write queries that retrieve, update, or delete data stored in a database, but in terms of the application's object-oriented structure rather than raw database tables. JPQL uses entities and their relationships, making it easier to work with complex data models. It is part of the Java Persistence API (JPA) and helps manage data efficiently while keeping the code clean and maintainable, bridging the gap between Java objects and relational database data.
