Integrated Database is a rather complex VBA example program for producing a materials list with an integrated Microsoft Access database. The tip serves more as a useful example for study by VBA students than as a utility you can put right to work. Supplied by Andrew Maser and written according to in-house standards at McBride Engineering, it demonstrates quite a few VBA features, such as how to interface with an Access database and how to automate the creation of a bill of materials for cost-estimation purposes.
