I have a large main table in my database, as well as several small tables which have been generated from the original table based on wave of data collection. (for example, main Table A contains names and addresses of study participants for rounds 1-5, while tables B, C, D, E, and F contain names and addresses of study participants for each individual wave). What I want is when someone enters data in table A, for the identical fields in tables B-F to automatically update without having to run an update query. Is this possible?
