Additional data not stored in the database - you might need to calculate information to add value to the database. For instance, a listing of students might include their grade point averages. You may also want to include summary statistics, like sums, counts, and averages. In addition to defining the content and format of the data in the report, you will also need to make decisions on the appearance of the report. Modern Windows-based DBMSs give you much flexibility to define things like fonts, colors, graphics, and other elements to improve the appearance of the report.
Reports also have on each page a header and footer.
You can define what appears on the top and bottom of each page. In writing your user manual, you can assume the user knows basically how to use the DBMS you choose. One of the most important features of the manual is instruction on how to enter data. Instructions have to be specific to make sure that data is entered consistently. Inconsistent data entry will make for unreliable results when output is generated from the database.
