To answer this question, you need to understand the concept of ACID properties in database management systems.
ACID stands for:
A) Access, Consistency, Isolation, Data - This option is incorrect because it does not correctly represent the ACID properties.
B) Access, Constrain, Index, Data - This option is incorrect because it does not correctly represent the ACID properties.
C) Atomicity, Consistency, Isolation, Durability - This option is correct. The ACID properties are:
Atomicity: This property ensures that a transaction is treated as a single, indivisible unit of work. It guarantees that all operations within the transaction are completed successfully, or none of them are executed at all.
Consistency: This property ensures that a transaction brings the database from one valid state to another. It enforces integrity constraints and rules, ensuring that all data modifications are performed in a consistent manner.
Isolation: This property ensures that concurrent transactions are isolated from each other, meaning that the intermediate states of a transaction are not visible to other transactions until the transaction is committed.
Durability: This property ensures that once a transaction is committed, its effects are permanent and will survive any subsequent system failures. The changes made by the transaction are stored in non-volatile memory (such as disk storage) to ensure durability.
D) None of these - This option is incorrect, as option C is the correct answer.
The correct answer is C) Atomicity, Consistency, Isolation, Durability. This option is correct because it represents the ACID properties accurately.
