the network. The interface program will accept the instructions from the output-
channel and pass these onto the external system. The frame model metadata then
receives the results from the external system and passes these back to the system via
the input-channel. Each external system has an identified input-channel and output-
channel. This input-channel and output-channel information is stored in the IRDS.
Figure 8.15 shows the coupling module data flow diagram.
Figure 8.16 shows the data flow diagrams of the developed EDS, which acts as
a knowledge-based system for new application.
Note: Each class (module) in the EDS has a number identifier to be used in
Fig. 8.17 .
Step 4. Application development.
After integrating personnel DB and HRM ES, users can ask the IHRMS to give
advice for a particular vacancy job. In this case, the EDS will ask users to key-in
