Sample IHRM interactive session
the IHRMS integrated environment (see Fig.
8.16
). Modules 1 to 7 represent the
personnel database, HRM expert system, personnel coupling class, HRM coupling
class, availability active class, average-grade active class, and synonym integrated
class. Figure
8.17
identifies how these modules integrate with the process flow.
The basic mechanism to deal with virtual attributes, which applied a method one
attribute at a time, will cause a heavy communication traffic problem. To minimize
traffic, a cache or “batches up” communication mechanism is needed.
Figure

,

, and

shows a prototype of the IHRMS. The source DBS
provides personnel skill information. The source ES provides selection criteria. The
integrated synonym table integrated class, availability class, and average-grade
class provide connectivity among coupling classes.
