Connection Imperative Implications & Challenges The ability to react on information  Always up to date information Adapt rapidly to changing business  Mandate to connect “islands” of information Integrate the virtual company  Multi-system, multi-company, multi-audience

Company A The Integration Challenge Remote Office/Consumers MobileEmployees Company B Customers Partners Suppliers Remote Office/Consumers MobileEmployees Business demand = everything connected

IT Challenges Integration “hurt” reached breaking point Lack of integration Systems not designed to work together Interoperability an afterthought Expensive, hard, time consuming, brittle Current model can’t keep up with business

Business Process Integration Challenges Different OS platforms Different application communication protocols  IIOP, RMI, DCOM,.NET Remoting… Different network protocols  TCP/IP, SNA… Different document formats  EDIFACT, CSV, XML… Different document definitions  SAP.Order ≠ JDEdwards.Order Different business processes  AKZO.ProcessOrder() ≠ DOW.ProcessOrder() Maintenance expensive  ~ $7 per business application $ spent

Business Process Integration Web services only part of solution… They provide a solution for:  Network protocol independancy  HTTP anywhere  Platform independancy  On any OS platform  Application platform independancy  SOAP anywhere  Document format independancy  XML anywhere But in reality…  Not all apps use web services…  No standard XML.Order… (only branche specific)  No standard business process…

Messages Tools Within Visual Studio.NET:  Pipeline Designer  Used to create custom pipelines  BizTalk Editor  Used to create XSD message schemas  BizTalk Mapper  Used to define mappings and XSLT transformations between message schemas

BizTalk Mapper An Example Map

Business Process Designing Orchestrations Define the operations in a business process using shapes  Compile into standard.NET assemblies Example shapes:  Decide: an if-then-else statement  Loop: performs an action repeatedly  Send: sends a message  Receive: receives a message  Parallel Actions: performs multiple operations in parallel

Business Process Designing Design Tools Within Visual Studio.NET:  Orchestration Designer  Used to organize shapes that define a business process Within Visio:  Orchestration Designer for Business Analysts  Orchestrations can be imported and exported between this and the Orchestration Designer

Process Implementation State Construct Message: allows declaring message variables, then setting their values An orchestration’s state is automatically stored and reloaded as needed MessageBox State

Scope Y: Long-running ERP Application Process Implementation Scopes Scope: supports transactions  Atomic: recovery via rollback  Long-running: recovery via compensation BizTalk Server 2004 Engine x 2) Attempt update, fail Scope X: Atomic CICS Application.NET Application 1) Update and commit 3) Compensate

Process Implementation Correlation Routes messages to an orchestration instance based on their contents  Doesn’t require the orchestration to block waiting for a response message BizTalk Server 2004 Engine PO# 5978 Purchase Order...
