Question
Which property ensures that intermediate transaction results are hidden from other concurrently executed transactions?
Solution
The property that ensures that intermediate transaction results are hidden from other concurrently executed transactions is known as Isolation.
Here are the steps to understand this:
-
In the context of database transactions, there are four key properties often referred to by the acronym ACID. These stand for Atomicity, Consistency, Isolation, and Durability.
-
Each of these properties guarantees certain aspects of transactions to ensure the reliability of data in a database.
-
The Isolation property is the one that ensures that the intermediate state of a transaction is invisible to other transactions. This means that no transaction can see the intermediate results of another transaction.
-
For example, if you have two transactions running concurrently where one is transferring money from one bank account to another, the Isolation property ensures that the second transaction cannot see the state of the first transaction until it is completed. This prevents data inconsistencies and conflicts.
-
Therefore, the Isolation property is crucial in multi-transaction environments to maintain data integrity and prevent conflicts.
