Databases have been used widely for many years, now. Databases using user-centered design not only have utility, but also improved usability. The usability problems of a database often occur due to lack of well-documented and well-established design guidelines and heuristics. These problems lead to increased errors, user dissatisfaction, and often user abandonment. The Breast SLN database was examined for usability compliance. This paper demonstrates, through the breast SLN database, one approach to analyzing and redesigning healthcare databases. In particular, it shows how a system that was developed without considering usability principles can be redesigned to create a system utilizing good human user-centered design guidelines, heuristics, and theories.
