Question

Why is there usually no control goal called update validity?

a. Input and update completeness achieve update validity.
b. Input validity guarantees update validity.
c. Update accuracy guarantees update validity.
d. Input accuracy achieves update validity.

Answer 1

The correct answer is option a, Input and update completeness achieve update validity.

Update validity refers to ensuring that the data being updated is accurate and consistent. Input and update completeness means that all necessary data is provided and all necessary fields are updated, which helps to achieve update validity.

For example, if a database is missing certain fields or if not all fields are updated during an update operation, then the update validity may be compromised.
