You could, of course, store this entire list in a spreadsheet. If you wanted to find data based on complex criteria, however, the spreadsheet would present problems. If, for example, you were having a “Johnny Rotten Night” party featuring music from the punk rocker, how would you create this list? You would probably go through each row in the spreadsheet and highlight the compact discs from Johnny Rotten’s bands. Using the data in Table 2-1, you would have to hope that you had in mind an accu- rate recollection of which bands he belonged to. To avoid taxing your memory, you could create another spreadsheet listing bands. | Chapter 1 Databases and Database Users Addison-Wesley is an imprint of PEARSON Copyright 2011 Pearson Education Inc.
