1. output content reporting frequencies and presentation output design fundamentals the cornucopia case portfolio project Systems Analysis and Design for the Small Enterprise section III Design

2. Chapter Objectives When you complete this chapter you will be able to: Match different users with the appropriate output content and presentation frequency Design multisourced outputs that rely on sophisticated file-sharing capabilities of 4GL application software Distinguish between periodic and on-demand reports Provide a way for users to design and create their own extemporaneous output Develop resource requirement estimates associated with output design

3. Output Content Output content depends upon user needs Output content may provide strategic, operational, and/or detailed information Access to different output content may require password protection A menu hierarchy can help the small- enterprise user access appropriate outputs

7. Reporting Frequencies and Presentation Many outputs are generated at predictable intervals, while others are generated in response to a user request Event-driven computing gives users more control over output operations: –when to create outputs –output formats (hardcopy, softcopy)

10. Output Design Fundamentals JAD sessions increase the user’s influence in the definition of output content and the presentation (design) of that content Analysts and users work with electronic prototypes of both input and output products

13. Structured Query Language (SQL) Structured query language allows the user to interrogate a relational database, provided the user understands the detailed structure of the database SELECT ot_amount from payroll WHERE empID = 12345 AND date = {05/10/2004}; Query-by-example (QBE) is a user-friendly SQL builder TECHNOTE 9-2

15. Figure 9-9: Output Design Steps List the system outputs identified on the USD and DFD Add one report for each master file and each transaction file Add other reports identified during JAD activities Evaluate each report its periodicity and output format Develop a general output design template for hardcopy and softcopy outputs Review your output list and deigns with the user and make revisions as necessary Create sample outputs for further review with the user

18. Chapter Summary Event-driven, user-friendly, visually oriented computing affects output design The more involved users become in output design: –Input error rates decline –Output demands become more specific –Processing options must be more flexible Output content greatly influences processing requirements
