Discussion
Because of the importance of making data model changes correctly, many professionals are ________ about using an automated process for database redesign.
Answer: B
Correct answer: skeptical
Automated tools can generate the DDL for a structural change, but they cannot know what the data means, which values will fail a new constraint, or what the applications expect - and a mistake against live data may be irreversible. Practitioners therefore use such tools to draft the change and then review, test and often rewrite it by hand rather than trusting the output.
