Write a use case description for the PRODUCE HARDWARE SOFTWARE CROSS REFERENCE REPORT use case. Use the use case diagram to determine the heading information, making any reasonable assumptions. The steps would be to read a software record, use that information to read the hardware-software relational table, then read the hardware record. Use the hardware record to print a line, accumulating totals. Print subtotals and grand totals.

This is a medium priority, low risk activity. Preconditions are that all the information must have been previously added to the appropriate database tables. Postconditions are that the report has been printed. Assumptions are that all the information on the database tables is correct. A success guarantee would be the report has been successfully created. A minimum guarantee would be the report could not be printed. The objectives met are to produce information about what software is found on which machine. Outstanding issues are what if the software is older and is not currently installed on any machines, how should the report be produced: printed, on a PDF file, or should it really be a query for one software package.
