This time I've got consent from Adrian Massey - http://adrianmassey.no-ip.org/web1/index.php - to post some of his horse racing data. The RaceODB.Zip contains an 128k OPK with three ODB files on it. Jockeys.ODB 418 Records, Trainers.ODB 536 records, Horse.ODB 1028 race favourite records Jan to November 2018. So anyone interested in horse racing and looking to practice working with multiple related databases has plenty to go at. If you need you can break open the OPK in Jaaps OPK File Editor.
If for example you were considering the 14:05 at Newcastle (today) the 1st December 2018 and wanted to consider the favourite Buveur D'Air ridden by B.Geraghty and trained by N Henderson. You could cross reference the databases to find..
Buveur D'Air was the winning favourite at Sansown on 3rd Feb, with Jockey B.Geraghty placed 142 times from 386 races was trained by Nicky Henderson who has been placed 224 times from 464 runners.
I'll let you know later how it went on.
Anyway again sincerely and in good faith Martin
