To maintain optimal performance in a high-user environment, which technique should a database administrator consider?

• A. Table partitioning
• B. Table locking techniques
• C. Stored procedures
• D. Backup scheduling

Answer: (B)

In a high-user environment, maintaining optimal performance is critical, and utilizing effective table locking techniques can help manage data concurrency and integrity. Table locking allows the database administrator to control how multiple users interact with data simultaneously, which is essential when many users are accessing or modifying records at the same time.

When locks are appropriately managed, they help prevent issues such as dirty reads, lost updates, and other concurrency problems that can arise in a high-traffic database. Utilizing techniques like row-level locking or optimistic concurrency control can significantly enhance response times and reduce the chances of contention between processes. This is especially important in systems where transactions need to be atomic, consistent, isolated, and durable (ACID properties).

Although other choices like table partitioning, stored procedures, and backup scheduling are also important aspects of database management, they do not directly address the immediate performance impact on concurrent user access as effectively as managing table locking does. By focusing on locking techniques, a database administrator can ensure that the database continues to perform efficiently even under heavy user load.
