Towards Total Business Integration: The XMLbus


Total Business Integration

Required for:• Integrated electronic business scenarios

(B2B, B2C, A2B,…)• Building virtual and distributed enterprises

Principal Problems:• Information exchange• Process integrationCommon infrastructure


Interaction between Partners

• In many cases, a common runtime infrastructure does not exist(e.g. CORBA to CORBA via IIOP)

Solution:

• Introduction of portals who act as information gateways

• Using self-describing message formats


Example: Virtual Enterprise

Processes


Interaction Technology (today)

• Message technology– EDI, EDIFACT– Message Queues

• RPC technology– DCE– CORBA

• Web technology– XML– SOAP


Interaction Technology (future)

• Transparent multi-protocol communication– Intra-enterprise support

• tightly coupled - IIOP• loosely coupled asynchronous - JMS• loosely coupled synchronous - HTTP/SOAP

– Inter-enterprise support• loosely coupled synchronous - HTTP/SOAP

• Service definition language (SDL)• UDDI for Discovery/Registration


IONA XMLbus

• Multi-protocol communication

• Common agreement through metadata

• CORBA-like invocation architecture

• Plus iPortal Integration Server providing:– Routing between different protocol systems– Message transformation & adapter– Process management and control– System / process definition repositories

ART Architecture

• ART microkernel: common functionality(invocation, marshaling, exceptions, …)

• Additional functionality through plug-ins(transactions, security, …)

• Further functionality through personalities:– Orbix 2000: CORBA, IIOP– Application Server: J2EE, EJB– XMLbus: XML/SOAP, SDL, UDDI, PE

• All personalities work transparently together

Summary

• Total Business Integration requires a multi-protocol platform plus process management capabilities

• CORBA provides powerful high-level services

• XML Technology provides maximum interaction flexibility

• Merging both provides best Platform
