I can create Excel based (using VB code) applications that match professional databases, but are simple to use with elegant interfaces. Excel based applications use very less space (2 MB for a large sized application). However these are stand alone (not web based). But these can be extremely useful for individual/ small group organizations. I have created one application - w_Docket, which is a civil engineering application for estimation, BOQ, Workslips, material requirements etc.
