A book is due three weeks after it was borrowed and comes back within 26 days, so about one in five is late; a few are never returned, and the last loans of 2025 are still out. Fines are charged on a share of loans -- which loans is drawn, not worked out from the dates; a fine never exceeds the cap of its policy, a payment settles its fine in full, and what a fine shows as paid is the sum of its payments. Opening hours are drawn per row, so a branch can list the same weekday twice -- a good table to deduplicate.", "domain": "education", "shape": "transactional", "useCases": [ "sql-practice",
