OMG - EDOC Enterprise Distributed Object Computing
Bringing together business goals, standards, processes and technologies for the e-enabled enterprise
2
Integrating Enterprises, People & Systems - Worldwide
Enabling e Using Internet Technologies
3
Integrating Enterprises, People & Systems - Worldwide
Business Requirements Virtual Enterprises Enterprise Integration (EAI) Supply-chain automation (B2B) Customer Integration (B2B) Web deployment (B2C) Internet Marketplace (B2C) Collaboration and Integration
4
The dynamic reality The information system must facilitate;
Rapid realization of business goals Integration of independent processes and systems Multiple and Changing business requirements business processes technologies standards enterprise boundaries partners
5
The e-enabled enterprise
Has a competitive advantage in its capability to embrace collaboration and change
6
Embracing collaboration and change
We need to extract the meat from the buzzwords And figure out how these concepts fit together To e-enable the enterprise Web Services Messaging & Events Model Driven Architecture EAI Open Collaborative Enterprise Components Middleware Repositories Shared Data Metadata Workflow
7
Business & Technology Coupling
“Open B2B” Ad-hoc business Collaborative Components EDOC Model (UML) Internet Computing Model ebXML Soap “Community B2B” - Business Partners & Independent Divisions Traditional EDI Events & Messaging JMS MQ-Series Synchronous Transactional RPC Corba EJB Integration within a managed domain Shared Data SQL IMS-DB Integration or production of an application
8
The role of open systems in the enterprise
Supporting open distributed computing while meeting local requirements
9
Enterprise boundaries are not static!
The “open domain” “The Enterprise” Independent domains collaborating via open standards No assumption of “the same thing” on both sides! Appropriate inside and outside the enterprise (EI & B2B) Requires business (process collaboration and information) and technical (middleware) standards The open domain needs a point of ownership in the enterprise The Enterprise Enterprise boundaries are not static!
10
The Internet Computing Model
Portals Business Party Business Party Collaboration of independent entities Document exchange over internet technologies Large grain interactions No required infrastructure * Long lived business processes Business transactions
11
Requirements for the “ICM”
Contract of Collaboration Shared business semantics Meta-Model (EDOC-ECA) and representation (I.E. XMI, ebXML-BPSS) Shared Repository for Contracts (MOF, UDDI, ebXML) Connectivity (middleware) which meets requirements of the contract Implementation of each contract role providing connectivity (application server) Business Partner Business Partner Instance Data Repository Contracts (Metadata) Contract of collaboration can be mapped to the format of various technologies. (ebXML, Soap, .NET)
12
Two levels of interoperability
Instance data and interoperability Business Partner Business Partner Biztalk ebXML Bridge Over Soap Over Soap Metadata (contract) interoperability .NET ebXML BPSS Purchasing Model Normal Form Each can be transformed
13
Drilling down – inside a role
The open domain should make no assumptions about the “inside” of a role. Inside one role you frequently find more collaborating “parts” of the enterprise - the same model may be used Until you get to system inside a managed domain Shared resources (DBMS) Common Management Frequently a legacy system Inner Role Legacy Inner Role Domain Inner Role Cust
14
Collaborative Business Semantics
Defined: The processes, information and contracts of interaction between collaborators within a community Collaborative business semantics are a valuable long-term asset Captures information and process Requires ownership and support in the open domain Do not put this valuable asset in a (transient - one size fits all) technology specific form Use technology independent models (MDA) Map to the technology of the day (E.G. DTD)
15
Required support for the open domain
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, EDOC...) How to represent shared processes and information Repositories Finding services, models and components for design time and runtime integration
16
Standards for Global Internet Computing
XML WSDL UML4EDOC SOAP .NET BPML XML-Schema
17
XML Standards XML Schema & DTD Soap Description and packaging of data
Basic messaging and packaging Extensions for Soap-RPC with WSDL May be extended to support collaborative messaging
18
Vision EDOC (a UML Profile) ebXML
Provide an architecture for open collaborative computing Simplify the development of component based distributed systems by means of a modelling framework, based on UML 1.4 Provide a platform independent, recursive collaboration based modelling approach supporting multiple technologies. Embrace Model Driven Architectures (MDA) – Provide design and infrastructure models and mapping ebXML Creating a single global electronic market Includes process specification, transport and repositories

Standards for collaboration
EDOC-ECA ebXML-BPSS Business Collaborations Yes – Community Process Yes – Multi Party Collaboration Contract of Interaction Yes – Protocol with Choreography & Object Interface Yes – Binary Collaboration with Choreography and Business Transactions Content Model Yes – Document Model Uses external forms, such as XML Schema Recursive Composition Yes – Recursive Composition into Enterprise No – Only “B2B” Detail sufficient to drive communications No – Requires technology mapping Yes – As ebXML transport. BPSS includes timing and security parameters. Computing Models Supported Internet document exchange, entities, business processes, objects and events Internet document exchange

25
Summary of points thus far
We must enable the emerging Internet Computing Model Loosely coupled roles exchanging documents based on a contract of collaboration Web need interoperability at two levels Messaging for the data Metadata for the contract of collaboration, stored in repositories This model of collaborating roles is recursive, extending into the enterprise, into managed domains and into applications Inside the enterprise we want to include resources entities, business events and business processes Supporting the open domain has some required parts and can be augmented with a “treasure chest” of tools and infrastructure Between EDOC & ebXML we are covering B2B and intra enterprise

The model of things Data Inside a “shared domain”
ECA Entity Profile The model of things Data Inside a “shared domain”
34
Adding Entities Entities are added to manage entity data
Entity Roles are managers that provides a view of the same identity in another context The Entities have ports for managing and accessing the entities Non-entities which are owned by (aggregate into) an entity are managed by the entity
35
ECA Business Events The model of when…
Loosely coupled integration within the enterprise and with “aligned” business partners

Business Component Marketplace
The business component marketplace is projected to be a 10b market in 5 years Consider the value of XML components that wrap popular legacy New application functionality built from components Components for integration and transformation XML and web services makes an excellent basis for such components Technology components, such as for repositories and DBMS Marketplace my be inside the enterprise or commercial

High level tooling & infrastructure
MUST BE SIMPLE! We must be able to create better applications faster We must separate the technology and business concerns, enable the user Tooling + Infrastructure Executable models are source code Tooling must be technology aware Infrastructure must support tooling, not manual techniques Model based component architectures

56
Generated Artifacts Artifact generation involves multiple tools
Implementation Artifacts (EJB Examples) Class Objects Jars,Wars,Ears Java Source Homes, SQL Stubs, Skeletons, Managers, Helpers, Holders, Primary Keys Interfaces Descriptors BeanInfo ,Editors. Documentation Serialization, . Persistence Management M0/M1 XMI/DTD Business Object Implementation Logic Artifact generation involves multiple tools EJB Container provider;Deployment tools;Packagers; java development tools(IDE);persistence provider;… Typical per PIM Classifier 0-20% manual override
57
Reverse Engineering model disposition navigation algorithms
PIM Native artifacts model navigation Production rule engine disposition process Native meta-model is platform-specific XML DTD/Schema; java introspection; SQL tables; legacy model; etc. Map navigates the native meta-model, populates PIM Limited semantic recovery Information and middleware models work best
