I am using a local Access database and have a tough question, my application allows many users to add data to the local database. I want these users to have the option to exclude other users from seeing their current record. Currently I have four text fields that I use to store 200+ User ID's (5 CHAR long) (these are the excluded ones). I then have to use the software to extract weather or not a user is allowed to view that record. Can someone please give me a better way.
