Only operations that meet data validity standards are allowed. For instance, systems that record checking accounts only allow unique check numbers for each transaction. Any operation that repeated a check number would fail to insure that the data in the database is correct and accurate. Network failures can also cause this type of data problem.
A) Atomicity
B) Consistency
C) Isolation
D) Durability

Question

Quizplus · Accepted Answer

The concept of allowing only valid data to be recorded in a database pertains to consistency, which ensures that only transactions that meet certain criteria are executed, preventing invalid or inconsistent data from being stored in the database. This helps maintain the accuracy and integrity of the data. Atomicity refers to the principle that a transaction must either be entirely completed or entirely rolled back if an error occurs. Isolation pertains to the degree to which transactions are separated from one another to prevent interference. Durability refers to the principle that once a transaction has been committed, it will remain so, even in the event of a system failure. While all of these principles are important, only consistency is directly related to the issue described in the prompt.
