Queue, uses the information in the event to build the message and finally deletes
the event from the event queue.
The event daemon puts the message it has built onto the data queue and adds an
instruction to the Control Queue
builds an HL7 message based on data pulled from Chronicles
Data Queue (Outgoing Message Flow) - ANSWER- contains the full text of the

Comm Daemon (Incoming Message Flow) - ANSWER- -listens constantly for
messages coming into the system
-validates MSH-11 and MSH-12 before accepting it, storing it in the data queue,
and adding instruction to the control queue
-sends or receives acknowledgments over a TCP/IP connection
Control Queue (Incoming Message Flow) - ANSWER- processed by the Filer
Daemon
Filer Daemon - ANSWER- pulls an instruction from the Control Queue, retrieves
the corresponding message from the Data Queue, and then attempts to file the
message.
Filing means that the Filer Daemon attempts to store the data in Chronicles.
If the filer daemon is successful, the data is added to the appropriate records in
Chronicles.
When there is a problem, and the data in the message cannot be filed, an
interface error message is logged
Translates HL7 data into something that can be stored to the database
When the filer daemon attempts to process a message, there are three things that
can happen - ANSWER- 1) it files the message into Chronicles, possibly with one
or more warning or notification errors
2) its unable to file the entire message because there is something critically
wrong with the message. This is indicated by a fatal or critical error
