The database requires a PC running Windows (and probably MS Office) or a Mac that can boot to Windows/run Parallels, etc. I can create a "run-time" installation of the database that basically packages the Access engine so you do not need the program. http://youlookfab.com/welookfa.....nalysis-q1 has examples of the forms and some of the calculations. One advantage of a database is you can select certain categories (like tops and toppers, but not bottoms) to look at wears, etc. I added in CPW calculations and have a host of other features (I am interested in tracking my wears, my purchases, etc so that's all in there). I like doing databases and I'd frankly be grateful if someone else were interested- it's a lonely field!
