Creating the jcdPsSelect Business Rules

The

jcdPsSelect

Collaboration implements the Input Web Service Operation to read the

TriggerPsSelect.in

file. It then copies the database resultset (as noted in the prepared

statement query) into the

otdInputDTD_DBEmployee

OTD and selects all available

records from the database. The Collaboration also writes a message to

JCD_PsSelect_output0.dat

to confirm when records are selected, or when no records

are available.

The

jcdPsSelect

Collaboration contains the Business Rules displayed in Figure 33.
