SYSE.34:4.1 - Recover meaning, consumers and authority
Describe the old and proposed values using the application’s meaning, including null, empty, ordering, precision and identity distinctions that matter. Define a correspondence and any inverse. Identify inputs that cannot be represented or carried back without loss; do not hide them behind a convenient conversion.
Find every relevant writer and reader, including jobs, imports, replicas, recovery tools and infrequent clients. Recover the actual database/storage edition, constraints, triggers, isolation and permission conditions that the procedure will use.
Obtain the required meaning and acceptance limits from their holders. The platform can support the mechanism without deciding which information may be lost or how long the business can operate without the service.
