LOCATION: HOME PAGE: DATABASES IN DISGUISE Excel as a Flat File DatabaseRecall that a database was defined as a set of data or information organized into one or more categories Because Excel spreadsheets are set up in rows and grids, many users use that as a way of organizing data. A Flat File List of PresidentsConsider a history class that may want to refer to a list of U.S. Presidents. With Excel, you can use columns to specify categories about the presidents, then rows for each president.
Fields and RecordsThis is now a flat-file database file. Each column specifies a field and each row is a record. As you will see in the next page on comma and tab delimited data, an Excel spreadsheet arranged with categories on top and items in rows is ready to be imported into most other database applications. SortsAs your list gets longer, you may find that you may want to sort the data by different columns. This can be done by highlighting the information, then going to Data » Sort and specifying a sort column. CalculationsExcel has many numeric, statistical and text based functions which allow you to generate calculated data based on data in a particular cell. If you add a column in which you perform a function, then you have created a calculated field column. Charting and GraphsAdvanced users often use the Chart Wizard (go to the Insert » Chart ) to create different sorts of tables and graphs based on data in selected cells. Thus, Excel gives users many of the basic advantages of electronic databases without the higher learning curve associated with Access, Filemaker and other database applications. Teaching Ideas
