Database software such as SAS works differently than spreadsheets in that data is entered in individual records, and the records can then be presented in tabular format if the user so chooses. For example, in a database of client information, an individual record is created for each client with name, address and other pertinent information. The database can be used to print mailing labels for all clients, identify clients by specific characteristics -- such as, for example, all clients east of the Mississippi -- or present client information in tabular format.
While it may be true that some of the things mentioned above could be done in a word processor, spreadsheets have a huge advantage over word processors when it comes to numbers. It would be impossible to calculate multiple numbers in a word processor and have the value of the calculation immediately appear. Spreadsheets are also much more dynamic with the data and can hide, show, and sort information to make processing lots of information easier.
