B) A tool for managing Java EE applications
C) A framework for building web applications
D) A library for handling exceptions
Answer:
A) A module for simplifying data access using JPA
Explanation:
Spring Data JPA is a Spring module that simplifies data access using the Java Persistence API (JPA). It provides a repository abstraction layer that allows developers to perform CRUD operations and complex queries without needing to write boilerplate code. Spring Data JPA also integrates seamlessly with various JPA providers like Hibernate, EclipseLink, and OpenJPA.
With Spring Data JPA, you can define repository interfaces that Spring automatically implements at runtime. This greatly reduces the amount of code needed to interact with databases, allowing developers to focus more on business logic rather than data access details.
