Description: A JPA (Java Persistence API) transaction is a unit of work performed against a database, ensuring that all operations within the transaction either complete successfully or are rolled back in case of an error. This concept is fundamental in data handling in Java applications, as it helps maintain the integrity and consistency of information. JPA transactions are based on the ACID principle (Atomicity, Consistency, Isolation, and Durability), ensuring that operations are executed reliably. In JPA, transactions are managed through an EntityManager, which is responsible for interacting with the database. When a transaction is initiated, multiple operations such as inserting, updating, or deleting entities can be performed. If all operations are successful, the transaction is committed; otherwise, it is rolled back, preventing inconsistent data from remaining in the database. This mechanism is essential in applications where data accuracy is critical, such as inventory management systems or financial applications, where any error could have significant consequences.
