Which one of the following is NOT a principle of database processing.

Question

BlackTom AI · Accepted Answer

Analyzing the statement in the context of database processing principles, let's evaluate each option.
Option 1: 'Before attempting any structural changes, you must clearly understand what depends on it.' This aligns with best practices in database management, since dependencies guide impact assessment and prevent unintended consequences.
Option 2: 'A logical model must be completed to map all needed changes to the database' This is not typically deemed a universal principle of database processing. While having a logical model can be helpful, it is not a strict prerequisite in every scenario, and many pragmatic workflows proceed with iterative changes, implementation, and testing without completing a full mapping upfront.
Option 3: 'Before any structural changes, you must test those changes on a realistic sized test database' This reflects a core precaution: testing changes in an environment that mirrors production helps catch issues before deployment, reducing risk.
Option 4: 'You need to create a complete backup of the operational database prior to making structural changes' This is a standard safety measure in database administration to ensure rollback capability if something goes wrong during changes.
In summary, the second option stands out as the one that is not a universal principle, as real-world practices may vary in how thoroughly a logical model is prepared before changes, whereas the other items reflect widely accepted safeguards and dependency considerations.
