Chapter 1 Introduction : Data Flow

Data Flow
This section describes the flow of events for all the examples provided with the adapter installation.
Data Flow for Publication Service Examples
A diagrammatic representation of the data flow for the Publication service examples is given next.
Figure 2 Flow of Events for the Publication Service Example
1.
2.
The service sends the data to the adapter.
3.
The adapter publishes the data and the subscriber in TIBCO ActiveMatrix BusinessWorks subscribes to the data.
4.
The TIBCO ActiveMatrix BusinessWorks process writes the data to an output XML file.
Data Flow for Request-Response Service Examples
A diagrammatic representation of the data flow for the Request-Response service examples is given next.
Figure 3 Flow of Events for the Request-Response Service Example
1.
The TIBCO ActiveMatrix BusinessWorks process reads the data from an XML file.
2.
The client configured in TIBCO ActiveMatrix BusinessWorksrequests the data and the adapter gets the request.
3.
The adapter in turn invokes a Tuxedo Service, which reads from a file and returns the reply to TIBCO ActiveMatrix BusinessWorks.
4.
The Tuxedo Service writes the request to a flat file.
5.
The Tuxedo service then reads from a flat file.
6.
It sends a response to the adapter, which forwards it to TIBCO ActiveMatrix BusinessWorks.
7.
The TIBCO ActiveMatrix BusinessWorks process then writes the data to an XML file.
Subscription service operating in Conversational and Queue paradigms are similar to Request-Response service since they send a reply on a reply subject.
Data Flow for Subscription Service Examples
A diagrammatic representation of the data flow for the Subscription service examples is given next.
Figure 4 Flow of Events for the Subscription Service Example
1.
2.
The publisher configured in TIBCO ActiveMatrix BusinessWorks publishes the data and the adapter subscription service subscribes to the data.
3.
The adapter Subscription service in turn invokes a Tuxedo Service.
4.
The Tuxedo service writes the data to a flat file.
Data Flow for Request-Response Invocation Service Examples
A diagrammatic representation of the data flow for the Request-Response Invocation service examples is given next.
Figure 5 Flow of Events for the Request-Response Invocation Service Example
1.
2.
The service invokes the adapter Request-Response Invocation service.
3.
The adapter sends the request.
4.
5.
TIBCO ActiveMatrix BusinessWorks then reads the reply input file and sends a response.
6.
The adapter Request-Response Invocation service receives the response and forwards it to the Tuxedo service, which in turn writes it to an XML output file.
