Avicenna System Analysis and Design System Design4 Printed Output Types of Reports Types of Reports Detail reports: produces one or more lines of output for each record processed Detail reports: produces one or more lines of output for each record processed Detail line: is any line printed Detail line: is any line printed Subtotals and grand totals Subtotals and grand totals Control field: controls the output, when the value of control field changes, a control break occurs Control field: controls the output, when the value of control field changes, a control break occurs Control break: A control break usually causes specific actions to occur, such as printing subtotals for a group of records. Control break: A control break usually causes specific actions to occur, such as printing subtotals for a group of records. Control break report: A detail report that focuses on control breaks Control break report: A detail report that focuses on control breaks The sorting can be done by the report program itself, or in a pervious procedure The sorting can be done by the report program itself, or in a pervious procedure Can be quite lengthy Can be quite lengthy Better alternative is to produce an exception report Better alternative is to produce an exception report

A detail report with one printed line per employee. The report shows a simple detail report of employee hours for a chain of retail stores The report shows a simple detail report of employee hours for a chain of retail stores [1]

Avicenna System Analysis and Design System Design6 Printed and Screen Output Types of Reports Types of Reports This detail report contains the same data as the report in the pervious slide, but provides much more information. Control breaks are used to separate the data for each store, with subtotals and grand totals for numeric fields.

Avicenna System Analysis and Design System Design12 Printed and Screen Output Report Design Principles Report Design Principles Column Spacing Column Spacing Space columns of information carefully Space columns of information carefully Crowded reports is hard to read, and large gaps between columns make it difficult for the eye to follow a line Crowded reports is hard to read, and large gaps between columns make it difficult for the eye to follow a line Column should stretch across the report, with uniform spacing and suitable margins at top, bottom, right, and left Column should stretch across the report, with uniform spacing and suitable margins at top, bottom, right, and left Field order Field order Fields should be displayed and grouped in a logical order Fields should be displayed and grouped in a logical order Grouping detail lines Grouping detail lines It is meaningful to arrange detail lines in groups It is meaningful to arrange detail lines in groups Group header: A group header appears above the first detail line of a group. Group header: A group header appears above the first detail line of a group. Group footer: A group footer appears after the last detail line of a group. Group footers could include items such as a subtotal, an average, or a count of the records in that group. Group footer: A group footer appears after the last detail line of a group.
