Question

The concept of serializability in a database management system is related to

• A. Concurrency control
• B. Normalization
• C. E-R models
• D. Symmetric key

Hint:

N/A

Answer 1

The Correct Option is A

- Concurrency control: Serializability is a concept in database systems that deals with ensuring that the concurrent execution of transactions results in a database state that is consistent, i.e., the effect is the same as if the transactions were executed one after another in some order. This is directly related to concurrency control mechanisms in databases.
- Normalization: Normalization is the process of organizing a database to reduce redundancy and dependency, but it is not related to serializability.
- E-R models: E-R (Entity-Relationship) models are used to represent data and its relationships in a database, but they are not directly related to the concept of serializability.
- Symmetric key: Symmetric key refers to a cryptographic key that is used for both encryption and decryption, which is unrelated to serializability in database systems.
Therefore, the correct answer is 1. Concurrency control.
