list all the different fields in the usability problem records.

list all the other relations: projects, product versions, usability sessions, usability trials, critical incidents, usability specifications, benchmark tasks, user instructions, participant pool

----------------------------

The UPC tool is used closely with the Usability Data Base (UDB) tool. As a new problem is to be analyzed, a database record is created. As each part of the analysis is completed in the UPC tool, the results are put into the database record for the problem. = verbatim from UPC, paraphrase here.

Then: additional analysis of individual usability problems, plus analysis at the problem aggregate level (e.g., cost-importance analysis)

Future: visualization of population densities of usability problem type clusters (for a product, project, etc. or across related projects).
