Thanks in Advance,

Hi Prabhakar,
If you ask me for a canonical data model in XI, i would go with XSDs. They are easy to create/import & use in XI. Since XI uses SOAP as its wire format and the payload is represented as an XML, converting from the various application data formats to your CDM will be relatively easy. Detailed difference b/w BW & XI will run to pages starting right from the base architecture. Is there any specific feature you are looking to compare ?

Hi Saravana,
I guess prabhakar is asking about publish-subscribe model availability within SAP XI. When we look at other EAI tools like TIBCO, Webmethods or MQ Series, all these vendors provide pubish-subscribe feature where in the source schema is converted into a canonical (intermediate) document and will be published on to bus or published to broker from where the intersted listeners would pickup and convert it to target schema/document.
This basically boils down to multicast or broadcasting of the message, which reduces the development cost when there are multiple publishers or multiple subscribers.
More-over this architecture facilitates the addition of a subscriber(target) or publisher(source) in the future.
Do we have such feature available in SAP XI?
PS: By the way could you please give me ur yahoo id. hope u remember me. I am from accord+(teradata team)

Pub-Sub is not directly supported in XI..as its not a BUS arch unlike TibRV.But you can still do the conversions to a standard Canonical format like they do in Siebel UAN.But one unfortunate implication is that there is a situation for huge messages floating around in the engine.You could typically have 200 xml nodes in a single structure running into a few MBs of msg size(if you couple it with SOAP/XML headers of XI) but of which you might use only 20-30 odd nodes.

yes while integrating with database .
for exampe if i have multiple publishers and have two subscribers.I need to accept all the pubilcation formats and convert it into comman format(canonical) for one subscriber and for other subscriber i have to send directly with some changes.
Also cud you please tell wahat is the protocal used in XI for message exchange(like RV in tibco)
