I&#039;m using access for my asp site, as there won&#039;t be very many concurrent users. However, I am concerned when it comes to Database integrity in situations with concurrent users. Do I need to specifically code in database locking, whether row or table locking? I currently use queries to modify data in the database, not recordsets. <BR>Also, if locking is needed, should i then use Access 2000&#039;s MSDE Engine or the Jet Database engine? Is there a difference when implementing either in my application? I currently use Access 97, so i&#039;m not sure about upgrades
