1 All rights reserved, Copyright © INTAP Overview: Guide for applying RM- ODP with UML Profile for EDOC From Enterprise Model to Computational Model and + alpha July 24, 2002 INTAP ODP Technical Committee

2 All rights reserved, Copyright © INTAP Agenda Introduction Overview of using: RM-ODP Enterprise Viewpoint Language UML Profile for EDOC – Enterprise Model UML Profile for EDOC – Information Model UML Profile for EDOC – Computational Model Engineering and Technology Model Summary Q&A

3 All rights reserved, Copyright © INTAP Introduction

4 All rights reserved, Copyright © INTAP Introduction Problems Objective Approach Open Standards used RM-ODP UML Profile for EDOC Introduction of Healthcare joint project

5 All rights reserved, Copyright © INTAP Problems Things which make enterprise system development more complex: Endless development requests generated to meet a variety of requirements Requirements for integrating heterogeneous systems and technologies New requirements like enterprise collaboration and Web Services support pop up unexpectedly System integration requirements by mergers and acquisitions Understanding, development, and maintenance of enterprise systems are getting more difficult Is there any way to better handle or organize this enterprise system development?

6 All rights reserved, Copyright © INTAP Objective We need something for enterprise systems that: makes it easier to understand makes it easier to communicate between subject matter experts Some kind of guideline for users to achieve above is the objective.

7 All rights reserved, Copyright © INTAP Approach Divide and conquer is the approach to handle complexity Utilize usable International Standards and OMG Specifications for this purpose Develop guideline for using standards about: How to divide complexity Sample steps or process of thinking (development) What should be described in each divided area What pitfalls are With examples

8 All rights reserved, Copyright © INTAP Standards utilized RM-ODP (Reference Model for Open Distributed Processing) from ISO/IEC & ITU-T Viewpoints Fundamental concepts UML Profile for EDOC (Enterprise Distributed Object Computing) from OMG UML extensions based on RM-ODP viewpoint framework Business process, event, entity, relationship, component, pattern, technology mappings etc.

9 All rights reserved, Copyright © INTAP RM-ODP Reference Model for Open Distributed Processing ISO Standards & ITU-T Recommendations Developed initially as reference standards for developing standards for open distributed systems Better to consider now as vendor neutral distributed system description framework Being adopted by OMG (OMA, Model Driven Architecture) Object Oriented Distinguishing feature: Five Standard Viewpoints defined for any system description

10 All rights reserved, Copyright © INTAP Five Viewpoints Enterprise Purpose, scope, and policies (not necessarily means real enterprise) Could be considered as requirements specification Information Meaning and processing of information Information model and schema Computational Functional decomposition (close to application objects) Could be considered as object model or component models Engineering Infrastructure to enable interaction between computational objects Could be considered as infrastructure/middleware for distributed processing systems Technology Choice of hardware and software, and conformance

11 All rights reserved, Copyright © INTAP Target Enterprise Information Engineering Technology Computational Five Viewpoints

12 All rights reserved, Copyright © INTAP Five Viewpoints Viewpoint specification for each viewpoint For one target system, at most five set of viewpoint specifications will be developed Those five set of specifications have correspondence among them, because those are the descriptions of the same target system (descriptions just from different viewpoints)

13 All rights reserved, Copyright © INTAP Application of viewpoints Can start with any viewpoint, but it would be enterprise viewpoint if top-down approach for thinking and design is taken. Can apply at any granularity level For instance, at the level of: International industry systems National industry systems Participating companys system Customer management system within companys system Security systems Biomedical authentication system within security system … Therefore it is import to clarify which target you are specifying.

14 All rights reserved, Copyright © INTAP Application at various levels International industry consortium systems Participating companys system Customer management system Within a participating company Refinement

15 All rights reserved, Copyright © INTAP Application of viewpoints What is defined and NOT defined in RM-ODP Viewpoint Language: Defined Vocabulary to define viewpoint specifications Structuring rules NOT defined Notation: Could be text or any language or technique like FDT, UML, etc. Process or methodology: Could be anything. This is the reason we are working on the guideline

16 All rights reserved, Copyright © INTAP What does it look like? Take an example of basic model for Web Services Web Services User Web Services Provider Web Services Trader Registry like UDDI and ebXML s) Web Services Trader Web Services User Web Services Provider Register Lookup Use Common diagram used to explain

17 All rights reserved, Copyright © INTAP What does it look like? Enterprise Viewpoint Model Community: Web Services Community- Target domain, Objective Roles/Objects – Participants in the community Web Services Trader Web Services Provider Web Services User Web Services Trader Administrator Web Services Description Behavior Web Services export Web Services import Policy – Constraints and rules Web Services Export Policy Web Services Import Policy etc.

18 All rights reserved, Copyright © INTAP What does it look like? Information Viewpoint Model Information element examples Web Services Type Web Services Description … Invariant schema example for Web Services system Web Services Description is uniquely identifiable Dynamic schema example State transition of information elements within Web Services Trader Static schema example Initial state for Web Services Trader

19 All rights reserved, Copyright © INTAP What does it look like? Computational Viewpoint Model Component example Web Services Trader Component Lookup Register Link Proxy Admin Interfaces defined with IDL

20 All rights reserved, Copyright © INTAP What does it look like? Engineering Viewpoint Model Internet/Web Services Infrastructure Distributed Object style communication SOAP/XML Distributed or federated naming Various interceptors security management Intra Enterprise CORBA Infrastructure CORBA Core CORBA Naming CORBA Trading

21 All rights reserved, Copyright © INTAP App Server What does it look like? Technology Viewpoint Model Intra-net Web Server (Windows) Web App Firewall Client Internet Service Functions Legacy App WSDL Wrapper Intra-net Firewall Web Services Trader on Unix Firewall Stand-By Front End TP Monitor Web Services User Web Services Provider RDB

22 All rights reserved, Copyright © INTAP Systems to be built? If the target is to develop new system: Five viewpoints applied to entire target system If the target is to integrate existing systems: Five viewpoints applied to each of the existing systems (legacy systems) Try to think of integration at the same granularity level

23 All rights reserved, Copyright © INTAP New System Enterprise View Information View Computational View Engineering View Technology View System X Divide and conquer with standard five viewpoints Model or Specification Refinements

24 All rights reserved, Copyright © INTAP System Integration System A System B Enterprise View Information View Computational View Engineering View Technology View refinements Think at the same granularity level

25 All rights reserved, Copyright © INTAP UML Profile for EDOC EDOC Enterprise Distributed Object Computing RM-ODP applied to enterprise systems UML Unified Modeling Language OMG UML Profile Customized UML for specific domains UML Profile for EDOC UML customized for enterprise systems based on RM-ODP framework

26 All rights reserved, Copyright © INTAP Added value to RM-ODP In addition to divide and conquer, Since viewpoint description will be in UML, More precise description will be possible, A variety of UML tools become available for model based system developments (e.g. use of stereotype etc.), and Depending on functions provided by tools: Skeleton code may be generated from UML models Fast path to system development with tool-integrated IDE One realization of OMG MDA

27 All rights reserved, Copyright © INTAP Structure of UML Profile for EDOC Composed of the following sub-profiles Component Collaboration Architecture (CCA) Entity Profile Event Profile Business Process Profile Relationship Profile Pattern Profile

28 All rights reserved, Copyright © INTAP Structure of UML Profile for EDOC Enterprise viewpoint (CCA, Processes, Entities, Relationships, Events) Technology viewpoint (UML for J2EE/EJB/JMS, CORBA 3/CCM, COM, SOAP, ebXML) Part I: Technology Specific Models Part II: Technology Mappings Part I: Enterprise Collaboration Architecture (ECA) (Technology abstraction: FCM) Engineering viewpoint Part I: Pattern can be applied to all viewpoints Information viewpointComputational viewpoint (CCA, Entities, Events)(Entities, Relationships)

29 All rights reserved, Copyright © INTAP A Project A joint project experimentally utilizing RM-ODP and UML Profile for EDOC is underway. Dealing with Healthcare area Feedback is expected from participation/experience The guide is also work in progress for revision to reflect the feedback
