Neco 2022 Data Processing Question 1
Practice objective / multiple choice question 1 from the 2022 Neco Data Processing examination.
A company maintains 10,000 employee records, each occupying 150 bytes. To support fast retrieval by employee ID and also to generate reports sorted by department, the company considers three file organisations: 1. Sequential file (no index). 2. Indexed sequential file with a primary index on employee ID. The block size is \(512\) bytes and each index entry occupies \(12\) bytes. 3. Direct (hash) file with 2,000 buckets. Assuming the data occupy the same amount of storage in all three cases, which file organisation provides the minimum total storage (data plus index) while satisfying both the fast‑ID retrieval and the sorted‑by‑department reporting requirements?
