If you want the most sophisticated data base in the world , with heaps of data interigation modules , then you can`t go past the GTSi program from TRB (The Ratings Bureau)
http://www.trb.com.au

It is a tool that can be used to analyse form or test & create systems.

But be prepared to pay premo for this Rolls Royse of form compiler .
I personally use it & I am amazed what it can do.
They compile the form themselves , that way the form integrity is in tact .
There are some others that try to do similar but they rely on a second outside sourse for the data which you have to subscibe to separatly.
This can lead to file corruption if either party changes anything in their program.

It is the only one of its type that has a pre-post market as seen in newspapers.

You can single out a particular race number .
E.g. The number of top 3 ranked Favs that win in race 8 only with 8-12 starters which has a jockey on board who has placed on the horse which is racing no more than 16% greater distance & not going down in distance any less than 22% with a TAB No. of 2-6, had 5-40 career starts ,had no stewards report on previous start, finished within -5 to +5 lenths last 2 starts & is ranked in the top 5 average prize money.

Try doing that exercise manually 7 days a week & you would probably make human errors & go nuts in the process.
