Hi Benny!
I do have a database going back at least four years. It includes the form of horses, the race results (on the Vic TAB including the exotics, the pools and the price fluctuation like 15 minutes 10 minutes etc. as supplied by the TAB results). It is a huge database and it is in MSAccess format.
I do not know how much you know about databases and programming in general, so let me know what sort of a data you are looking for? I may be able to help you. We may come to an agreement!?
