Online Presentation: Java Persistence API (JPA) and Hibernate ORM

1. What is Data Persistence?

• Definition: Data persistence refers to the mechanism of storing data in a durable medium, such as a database, so that it remains available beyond the runtime of an application.
• Why It Matters:
  • Preserves application state.
  • Enables data recovery in case of system failures.
  • Supports enterprise-scale operations where data must be available long-term.
• Examples:
  • Storing user profiles in a database.
  • Saving application settings or transaction records.
