You don't actually need a full version of Access to run most of the applications we design. They can be run using the free "run-time" version of Access that is available from Microsoft.
Just an option that allows more flexibility than what is available with DBA itself. If you like, you can go to our website
www.ariaconsulting.net , go to the Services section, then Custom Application Solutions and there is a link there that will take you to some screenshots of applications that we have designed to work with DBA in MS Access.
