Summary:

A set of Run-Time object-oriented coupling metrics are defined in this paper and then compared to existing static metrics. The metrics are evaluated using a collection of Java Programs from the SPECjvm98 benchmark suite. The new dynamic metrics resulted in having large amounts of variance, showing that more research needs to go into them. There was good correlation shown between CBO and Ri since Ri is basically CBO done at run-time. Another interesting result was that there was negative correlation given between CBO and RDe. The results in general showed that the run-time metrics can complement the static metrics and with more work put into run-time metrics they could offer a new view of software.
