JPA Specification

JPA Specification is a part of Java Persistence API that provides a flexible way to build complex database queries programmatically. It acts as a set of rules and interfaces for defining how to fetch, filter, or manipulate data stored in a database. Instead of writing raw SQL, developers use Specifications to create reusable, type-safe query criteria that can be combined logically. This approach helps in constructing dynamic queries efficiently, making database interactions more maintainable, readable, and adaptable within Java applications.
