The CVT Company is a leader in the manufacture of work clothes. You are hired as database administrator for the company and your IT supervisor asked you to solve a retrieval speed problem they used to have with a large file for item records. Your supervisor mentioned that they have sorted the file but the problem didn’t improve, so they need to create a B+ tree index to solve the problem. Your supervisor outlined the way to do it: “The best way to accomplish this task is to scan the file, record by record, inserting each one using the B+ tree insertion procedure.” Being a fresh graduate, you noticed that since the file is already sorted there is a better way to do it. What performance and storage utilization problems are there with your supervisor’s approach? Explain how the bulk-loading algorithm provides a better alternative than the proposed scheme.
