Four worked buying briefs
These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Schema compatibility | Import required schema objects and extensions. | Every mandatory object is supported by the selected configuration. |
| Application transactions | Run representative critical read and write transactions. | Results and transaction outcomes match the application specification. |
| Restore drill | Restore a test backup into a separate environment. | The restored database passes application checks. |
| Cutover plan | Rehearse application reconnection and rollback. | The team can explain the cutover and recovery sequence. |
