The Fundamentals of Database Design To end up with a good ‘relational database’ application‚ you need to ask: Do I actually need one? If so‚ how far do you want to take it?

Analyzing Data Using Pivot Tables – An Example Remember assignment 5 where you were asked to compare Invoice amounts to Sales Order amounts? You had to create a query to join together 2 tables from an Access database. If the results of that query had been downloaded into an Excel file (a simple thing to do)‚ you could have used the Excel file and a Pivot table to help in the analysis. Before you try to follow this example‚ you should learn as much as you can about Pivot Tables from Microsoft’s
