3 What is EIA? What is EIA s Integration Broker? Presentation Agenda Definition of Business Process. What is a Business Process Manager? Case study: Integrating H P Process Manager (HPPM) with BEA elink (Tuxedo).

4 Enterprise Infor mation Architecture What is EIA? Projectto build internal infrastructure to support A2A (internal eai) and fra me w ork for B2B services. Major components are; Integration Broker Business Process Manager Application Server Platform

6 Enterprise Application Integration (eai( eai) Benefits: One single, common integration platform (better manageability) As soon as a component is connected to the bus, it is directly accessible for any present and future other component. Without EAI With EAI A B C A B C Bus D E F D E F N Applications N.(N-1) / 2 Connections N Applications Only N Connections 29 June 2001 Page 6

7 Enterprise Application Integration Benefits: Control and monitoring of data flow (security, auditing, postmortem analysis) Make physical network infrastructure transparent for applications Advanced data distribution schemes (eg. publish/subscribe) Guaranteed data delivery Allows development of new cross-application functionality Integrated applications can be easily replaced without affecting the whole infrastructure (adapters isolate the bus of the application specific interface). Provides an efficient back-office connectivity for ebusiness Reduced maintenance and development cost 29 June 2001 Page 7

8 Technical case for an Integration Broker Existing situation Integration Broker Business Process Manager Incoherent Data! Application A Application B DB Service Design? Difficult! DB Application C Application D 29 June 2001 Page 8

9 Software focused on enabling integration between multiple applications and services. What is EIA s Integration Broker? Asynchronous (loose-coupling) imple mentation acco mplished by use of a Message-Oriented (MO M) Integration Broker technology. Synchronous (tight-coupling) imple mentation acco mplished by use of CORBA technology. Dedicated to enabling highly available environ m e nt.

13 Start Conditional Task End process What is a Business Process? A series oftask,thatfulfilsome functionality Each task isperformed by a software application or person. Work is granular and atomic. Processes can be... Bounded by the enterprise (A2A) Across the internet (B2B) Intersected with WebServices

14 Software focused on defining and controlling w orkflow betw een multiple applications and/or services. What is a Business Process Manager? M aintains state of a process through the fullend-to-end lifecycle. Platform for defining fail-over and error recovery mechanism s. The Guardian Angel of application/service integration.

20 Step 2: W orkflow engine connects with Integration Broker. BPM Integration Broker Applications HR 2 Integration Broker Legacy

21 Step 3: Integration Broker connects to legacy system. BPM Integration Broker Integration Broker 3 Legacy HR Applications

22 Step 4: Legacy syste m performs task, returns results to Integration Broker. BPM Integration Broker Applications HR Integration Broker 4 Legacy

Needs interface to the J2E E platform, to extend BP M control over B2B, eco m merce and Web Services. Very useful Guardian Angel w hen implem ented in a co m plex and/or stateful application environ ment.
