Final answer:
The 'D' in ACID properties of database management systems refers to Durability, which ensures that changes made by a completed transaction won't be undone and will survive system failures. 'Durably persist' is the correct concept, meaning the changes are permanently recorded.
Step-by-step explanation:
The D in ACID properties stands for Durability, which refers to the assurance that once a transaction has been committed, it will remain so, even in the event of power loss, crashes, or errors. In a database management system, durability means that changes made to the database by a successfully completed transaction are permanently recorded and can survive system failures.
Among the provided options, the correct one is (d) Durably persist; Dovetail. However, 'Dovetail' is not a standard term associated with the ACID properties. Instead, the term 'Durably persist' accurately captures the essence of Durability in database systems. Once a transaction is committed, the changes should durably persist, which means the changes should not be undone and must withstand system restarts and crashes. Therefore, 'Durably persist' is the aspect that aligns with the ACID property 'Durability'.
