I created a solution for a client. The solution took a pile of their data and with a bunch of scripts, etc. produced analyses and reports. They liked it and wanted me to do the same thing with a different dataset. So I duplicated the database file, deleted all of the records and imported the new dataset (from a spreadsheet). Rinse and repeat. I now have four different files with four different datasets.
Everything works great, but the problem is that every time I fix or add something in a script, I have to do it four times. This is cumbersome and error prone. So maybe I didn't approach this correctly. Is there a better way?
