Q:

which of the following represents a set of properties that guarantee that database transactions are processed reliably in computer science ?

A) Buffer Cache B) ACID
C) Foreign Key D) None
 
Answer & Explanation Answer: B) ACID

Explanation:

ACID 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.
