- Question
which of the following represents a set of properties that guarantee that database transactions are processed reliably in computer science ?
Options- A. Buffer Cache
- B. ACID
- C. Foreign Key
- D. None
- Correct Answer
- ACID
ExplanationACID means (Atomicity, Consistency, Isolation, Durability) is a set of properties of database transactions intended to guarantee validity even in the event of errors, power failures, etc.
In the context of databases, a sequence of database operations that satisfies the ACID properties and, thus, can be perceived as single logical operation on the data, is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.
