Integrating H2 Database & JPA
Set up an in-memory H2 database and configure Spring Data JPA for data persistence.
Storing Data with Persistence
Welcome! In this lesson, we'll learn about data persistence. This is how applications save information so it's not lost when the app closes.
Think of it like saving a document on your computer. Without persistence, all your work would vanish every time you shut down.
Introducing JPA
JPA stands for Java Persistence API. It's a standard for managing relational data in Java applications.
JPA helps map Java objects to database tables, a process called Object-Relational Mapping (ORM). This lets you work with objects instead of writing complex SQL queries.
