Design Report Principles
-
Page headers and footers
-Every page should include a page header, which appears at the top of the page and includes the column headings that identify the data.
-The headings should be short but descriptive.
-
Column spacing
-You should space columns of information carefully.
-A crowded report is hard to read, and large gaps between columns make it difficult for the eye to follow a line.
Field order
-Fields should be displayed and grouped in a logical order.
-For example, the report shown in Figure shows the detail lines printed in alphabetical order within store number, so the store number is in the left column, followed by the employee name
Grouping detail lines
-Often, it is meaningful to arrange detail lines in groups, based on a control field.
-For example, using the department number as a control field, individual employees can be grouped by department.
Repeating fields
-Report design is an art, not a science.
-User involvement is essential, but users often don’t know what they want without seeing samples
Consistent design
-Abbreviations used in reports also should be consistent.
-For example, when indicating a numeric value, it is confusing for one report to use #, another NO, and a third NUM.

b. Exception reports
-Figure shows an exception report that includes information only for those employees who worked overtime, instead of listing information for all employees.
c. Summary reports
-For the personnel manager, a summary report such as the one shown in Figure would be useful.
