Spring Boot CRUD with MySQL & Spring Data JPA | 7 Java Interview Questions | Day 2

🚀 *Spring Boot CRUD Tutorial – Day 2 | MySQL Integration with Spring Data JPA* Welcome to Day 2 of the Spring Boot CRUD series by *Let's Rewind Experiences!* In Day 1, we implemented CRUD operations using an In-Memory Collection. In this video, we'll take the next step by integrating MySQL with Spring Boot using Spring Data JPA. Along with practical implementation, we'll cover 7 important Java Backend Developer interview questions. 📚 *Topics Covered:* 1. What is the role of MySQL Driver Dependency? 2. What is Spring Data JPA and why do we use it? 3. What is an Entity in JPA? 4. Why do we use @GeneratedValue? Understanding AUTO, IDENTITY, SEQUENCE and TABLE strategies. 5.
