Create Horse Racing Database from Excel

I have a horse racing Spreadsheet, I load the form into a sheet, every time I want to run analysis on those days racing. That sheet contains all the Data for the Race meeting, and 10 previous starts with all the stats for that race for that horse. I then have about 20 sheets, each sheet has information, that is used for calculations, IE each race track has its own sheet, that contains a rating for each distance and barrier so it can work out a score for the horses previous starts at that track , distance and barrier, and it also works out a score based on its race for the day. There would then be Sheets for Jockeys Races Class of Races Age etc. So the data base needs to be able to store all the horses race data that gets loaded each week, ( not duplicating, so it only adds additional race information ( There is a race ID Feild that will assist with that ) It has a heap of forumala's that works out a rating for every horse in the race, and it then frames a market, and provides the tips, The spreadsheet does all this, I just want it in a data base, so its easier to manage and it gives me Website Access, so I can login and use it from anywhere And I want it to be able to link to a website, so that I can essentially have a something like [login to view URL] But not as indepth being able to bring up the Race, and see the systems Top selections
