A spreadsheet uses rows and columns of numbers to create a model or representation of a real situation. Today, spreadsheet software, such as Microsoft Excel, provides tools to create electronic spreadsheets. As an added bonus, spreadsheet software helps you turn your data into a variety of colorful graphs. It also includes special data-handling features that allow you to sort data, search for data that meets specific criteria, and print reports. Spreadsheets are popular with accountants and financial managers who deal with paper-based calculations.

The disadvantage of spreadsheet software is that – aside from a few predesigned templates – you are responsible for entering formulas and selecting functions for calculations. If you don’t know the formulas or don’t understand the functions, you are out of luck.

Microsoft Access, FileMaker Pro, and ask Sam are three of the most popular examples of database software for personal computers. Database software stores data as a series of records, which are composed of fields that hold data. A record holds data for a single entity – a person, place, or event. A field holds one item of data relevant to a record. Your database software can help you print reports, export data to other programs, convert the data to other formats such as HTML.
Whether you print, import, copy, save, or transmit the data you find in databases, it is your responsibility to use it appropriately. Never introduce inaccurate information into a database.
