What components should be included in a status report?

The mechanism of annotated managed transactional behavior @Transactional in Java (for example, in Spring Framework) consists of several key components:

1. @Transactional annotation — indicates that a method or class should be executed within a transaction.
2. Proxy — created by the container (e.g., Spring) to intercept calls to annotated methods and manage transactions.
3. Transaction Manager (PlatformTransactionManager) — responsible for beginning, committing, and rolling back transactions. In Spring, it is an interface with implementations like DataSourceTransactionManager.
4. Transaction Definition — contains settings for the transaction, such as isolation level, propagation, timeout, and rollback rules.
5. Transaction Synchronization — mechanism to synchronize transaction state with resources (e.g., Hibernate sessions).

Example:

@Transactional
public void updateData() {
    // business logic executed within a transaction
}

When the method is called, Spring proxy starts a transaction, executes the method, and commits or rolls back depending on the outcome.
