If it is an Access database you could just open the DB in Access.You could also build you own database editor using ASP / ADO or download one.
If you go to www.aspin.com and type in database editor you will have many selections to choose from. Some are good and some are lame.
Using the compact/rebuild feature in Access is one of the more important things to do to keep your DB in shape. This can be done in an online editor so you don't have to download the entire DB.
