I used the term DSB when I was talking about formalising the BSB definition, for much of the same reasons talked about above. The reality is that each business domain has different requirements and moves at a different pace. If you are a "pure" SAP shop in ERP and a "pure" Oracle shop in HR then its pretty pointless not to use Netweaver and Fusion as your two DSBs in those areas. Also as one area upgrades to the "latest" of a given product this means that from a technology perspective they are disjoint from those that don't. My view is that the DSB -> DSB connection (via an almost etheral BSB) is the bit where standards are rigidly enforced, and inside given Domain areas you might have further levels of Turtles^H^H^H^H^H DSBs depending on the size and complexity of the organisation. Enterprise-wide Software is a myth. On 06 Apr 2007 08:01:38 -0700, Jerry Zhu <[EMAIL PROTECTED]> wrote:
Domain SB should be enterprise wide compliant in terms of common protocol, infrastructure services, common XML schemas, policies etc. A bad practice is that each dept build their own DSB without knowledge what other depts are doing. So yes, it is DSB but the same time it should be ESB also. --- Timothy Vibbert <[EMAIL PROTECTED] <timothyvibbert%40gmail.com>> wrote: > I would have to agree with Miko.
