What are the best practices for concurrency control in databases?

The best practices for concurrency control include using locking mechanisms, implementing timestamps, and optimizing transaction isolation levels.

Can you explain how locking mechanisms work?

Locking mechanisms prevent multiple transactions from accessing the same data simultaneously, ensuring data integrity.

What are the different types of locks?

There are several types of locks, including shared locks, exclusive locks, and read/write locks, each serving different purposes.

How do timestamps help in concurrency control?

Timestamps help by providing a way to order transactions, allowing the system to resolve conflicts based on the time of execution.

What is transaction isolation and why is it important?

Transaction isolation determines how transaction integrity is visible to other transactions, crucial for maintaining consistency.
