Figure 5.14 (in the attachment) shows a sequence of grant operations for a specific access right on a table. Assume that at t = 70, B revokes the access right from C. Using the conventions defined in Section 5.2, show the resulting diagram of access right dependencies.© BrainMass Inc. brainmass.com March 22, 2019, 1:25 am ad1c9bdddf
When B revokes the access right from C, first the line B-C will be deleted.
Next, the arc C-D that is labeled "t=30" will ...
Solution briefly explains how the resulting access right dependencies diagram will be obtained.
