yah, it should be able to do that. Each day, you add the entries of that day to a table, with a stamp of the day (say, 20021008 for 10/08/2002). When you want to see the available dates, you just do a SELECT DISTINCT Date FROM Table. Then, when you want to see the entries for 10/08/2002 day, just do a SELECT Users FROM Table WHERE Date=20021008.

Note that I'm not a database guru, but this should give you an idea how to proceed.
