Master Hibernate and JPA with Spring Boot in 100 Steps - Quick Introduction to JPA

The video introduces Java Persistence API (JPA), comparing it with JDBC and Spring JDBC. It explains how JPA simplifies database operations by focusing on Java objects and their mapping to database tables, eliminating the need for writing complex SQL queries. The video covers defining entities, mapping fields, and establishing relationships like many-to-many, one-to-one, and many-to-one. It also discusses different query methods in JPA, including JPQL, criteria queries, and native queries. The course promises a step-by-step approach to learning these concepts.

What is one of the main advantages of using JPA over JDBC?

• JPA is more complex to maintain.

• JPA simplifies database operations by abstracting SQL queries.

• JPA requires more SQL knowledge.

• JPA does not support object-relational mapping.

In JPA, what is the term used for Java objects that are stored in the database?

• Records

• Schemas

• Entities

• Tables

What type of relationship is described when a student can enroll in multiple courses and a course can have multiple students?

• One-to-Many

• Many-to-Many

• One-to-One

• Many-to-One

Which relationship type in JPA is characterized by a single review being associated with one course?

• Many-to-One

• One-to-One

• One-to-Many

• Many-to-Many

What is JPQL in the context of JPA?

• A method to write SQL queries directly.

• A way to write queries using Java entities.

• A type of database connection.

• A tool for database schema design.

Which querying method in JPA allows you to build queries using Java API?

• JPQL

• Native SQL

• Criteria Queries

• Stored Procedures

What is the purpose of using native queries in JPA?

• To use SQL directly for complex queries.

• To enhance object-relational mapping.

• To avoid using SQL entirely.

• To simplify entity relationships.
