Accountants can usemany different types of logic charts to trace the flow of accounting data through an AIS. For example, document flowcharts describe the physical flow of order forms, requisition slips, and similar hard-copy documents through an AIS. These flowcharts pictorially represent data paths in compact formats and therefore save pages of narrative description. System flowcharts are similar to document flowcharts, except that system flowcharts usually focus on the electronic flows of data in computerized AISs. Other examples of documentation aids include process maps, data flow diagrams, program flowcharts, and decision tables. This chapter describes all of these documentation aids, as well as some computerized tools for creating them.
