Dumps and traces are both used in debugging problems. However, their basic nature is very different -- a dump is a point-in-time snapshot of the system (hopefully at or near the time of an ABEND) whereas a trace is a time-based listing of commands (instructions) issued. Many dumps include some trace information since it can be helpful to know what was happening before the dump occurred.
