1 MDA for Enterprise Collaboration & Integration Enterprise Collaboration Architecture Cory Casanave
2 What is the Enterprise Collaboration Architecture? ECA is a profile of UML, a way to use UML for a specific purpose - it is an OMG standard That purpose is Internal and B2B collaboration and integration. You can also think of this as a modeling framework for enterprise computing ECA is part of the Model Driven Architecture (MDA) initiative of the OMG Using precise modeling techniques as part of the development lifecycle to speed development and provide technology independence ECA has been adopted by the OMG as part of the EDOC RFP
3 Problem Space Integration Nightmare Infrastructure, Version & Vendor lock-in Complex, divergent and manual development and deployment processes Typical solutions require buy-in (Lock-in) to expensive, pervasive and proprietary infrastructure
4 Goals A scalable and robust enterprise and cross-enterprise architecture Loosely coupled enterprise components Enable rapid provisioning of business solutions Simple, reproducible processes supporting reuse Technology & vendor independence Enable the integration and collaboration of multiple; Business units (internal and external) Customers Suppliers Systems Technologies
5 Solution Triad Web Services Corba Service Based Architecture Components J2EE.NET Model Driven Development OMG ECA Development Process Tooling & Infrastructure Standards
6 Technology Stew Web services.net C XML EAI Active Web pages EJB Java Beans Java Corba MQ-Series C++ SQL Cobol IMS CICS... Technology is transient, but we must embrace and adapt to it to provide meet current requirements
7 The new center The strategic core of you systems must be the business its self Only technology independent business focused models will survive the transience of technology and lock-in These models can become part of your source code, driving enterprise applications Enabler: Model Driven Architecture (MDA) with EDOC-ECA Extreme Modeling
8 ECA as the normal form MDA Mappings Web Services (WSDL) ebxml (BPSS) EDOC-ECA J2EE (Java RMI) The standard way to model and tool for multiple technologies.net MOM (MQ-Series)
9 Specification Interoperability ECA can represent and map to the semantics for multiple technologies Integrating the technologies and standards Mappings can include Corba.NET J2EE WSDL WSFL WSI Use EDOC-ECA to specify domain standards
10 Domain Standards Using ECA Core Components Use Map Web Services (WSDL) XBRL ebxml (BPSS) OAG EDOC ECA J2EE (Java RMI) Acord UBL.NET MOM (MQ-Series)
11 Automated Model Driven Architecture Profile (E.G. EDOC) Business Focused Model (UML) Infrastructure Mapping (E.G. ebxml) Tools Produce & Integrate Enterprise Components C Enterprise Components C Mapping is tuned to the infrastructure Framework & Infrastructure (E.G. ebxml) Framework & Infrastructure (E.G..NET)
12 Enterprise Components Enterprise Components must be independent While being able to interoperate with each other Making the information system a lattice of cooperating components Open Standards Open Standards Open Standards
13 Enterprise Architecture Supply Chain Web Browser EAI Applications & B2B E-Commerce Client Applications XML Corba EJB DCOM MQ Enterprise Components SQL DBMS, Client/Server & Legacy Applications HTTP Web Server Applications User interface and application logic go here Standard Middleware connects applications to components & components to components Business and data rules go here The data goes here
14 Legacy Wrapping Wrapping allows existing programs and data to work with and work as enterprise components Adapters

18 Multiple roles in a collaboration
19 Roles to Systems Framework, Middleware & Container Role Collaboration Component in Role Interaction Path Interaction (With Information) Implementation Operating System Net Hardware
20 Required elements for interoperability Connectivity standards and infrastructure Providing the enterprise bus (Intranet) http, Soap, ebxml Common processes and lexicon What goes on the bus - the real business value! Facilitating communities of practice Meta-model standards (UML, ebxml-bpss, ECA...) How to represent shared processes and information Repositories Finding services, models and components for design time and runtime integration
21 Standards for Global Internet Computing XML.NET EDOC XLANG BPML WSDL SOAP XML-Schema
22 ebxml & EDOC ebxml EDOC Transport Distribution Repository Runtime Collaboration Process Model Enterprise Integration Components Information Model MDA
23 JSR 159 Java Process Components Uses ECA (CCA) as the baseline component model Asynchronous document exchange Component composition A J2EE technology mapping for ECA Will make J2EE an excellent integration and web services platform
24 The WSEC RFP A Mapping from EDOC-Enterprise Collaboration Architecture to WSDL 1.1 with attachments and a SOAP binding. A Mapping from WSDL 1.1 with a Soap binding to the EDOC-Enterprise Collaboration Architecture. Any required extensions to the EDOC-Enterprise Collaboration Architecture to represent WSDL semantics.
25 EDOC Enterprise Collaboration Architecture The model of collaborative work

42 Summary Interoperability must exist for the contract of interaction as well as for protocols OMG has adopted MDA technology for interoperability and collaboration semantics based on UML Using MDA can help bring together divergent infrastructure and forms of specifications Processes are underway to provide mappings to a variety of middleware technologies Join with OMG to provide true interoperability with MDA and ECA
