$23\mathrm{.}2.$ A major information system has $1140$ modules. There are $96$ modules that perform con$-$ trol and coordination functions and $490$ modules whose function depends on prior processing. The system processes approximately $220$ data objects that each has an average of three attributes. There are $140$ unique database items and $90$ different database segments. Finally, $600$ modules

have single entry and exit points. Compute the DSQI for this system.
