16 Oct 2000 - Presented Papers

A Case study in Application Integration. Stijn Van den Enden, Business Integration Company and Erik Van Hoeymissen, Gregory Neven, and Pierre Verbaeten, DistriNet Research Group

A fascinating and clever way to use XML adapters and workflow to link two disparate legacy systems, a front office system built in Forte on Sun, and a back office system built with Unisys LINC.

Business Object Components? Erik Persson, Department of Computer Science, Lund Institute of Technology

Tough problems with fragile base classes make "object components" an oxymoron. This paper forced us to change the name of the workshop to Business Objects "and" Components: Design and Implementation.

Business Object Components in B2B architectures. Jean-Jacques Dubray, eXcelon Corp.

A leading B2B portal vendor architecture describes "business collaborations" as way to integrate enterprises where no central workflow or point of control is possible.

Case Study: Automating Business Rules at a Public Sector Financial Institution. Dean Mackie, Ontario Teachers' Pension Plan

A legacy system was enhanced for the web by building a parallel Java, JSP, XML frontend. The architects were annoyed that the primitive state of XML tools forced them to us Java and JSP, rather than a pure XML implementation.

Cross-Organizational Workflow Integration using Contracts. Willem-Jan van den Heuvel and Hans Weigand Tilburg University

The notion of "contracts" can be used for integration two enterprise systems with different implementation of workflow.

A Technology-Neutral Component-based Architecture for Enterprise Application web-Integration. Ali Arsanjani, IBM Global Services. (Ali is Chairman of our companion workshop, Best–practices in Business Rule Design and Implementation.)

An IBM consulting group has a framework that uses four patterns to implement components of any granularity. Workflow and rules are appropriately partitioned in this framework.

Guidelines for Developing Adaptive Plug-and-Play Business Component Systems based on the J2EE. Michael Fahrmair, Frank Marschall, Sascha Molterer, and Maurice Schoenmakers, Technische Universität München

The overhead and performance problems with using EJBs were assessed. The workshop consensus was that good architecture, good developers, and good patterns were essential to implementing scalable EJB applications. All of these are in short supply in an average development organization.

REA, a semantic model for Internet supply chain collaboration. Robert Haugen, Logistical Software LLC and William E. McCarthy, Michigan State University

The REA model (economic resources, events, and agents) is the state of the art in implementing accounting transfers within and between enterprises.

Transactional Business Process Servers: Definition and Requirements. Thomas Mikalsen, Isabelle Rouvellou, Stanley Sutton Jr., and Stefan Tai, IBM T.J. Watson Research Center and Mandy Chessell, Catherine Griffin, and David Vines, IBM United Kingdom Laboratories

Maintaining persistent state of components is essential for long transactions.

We will be publishing after the workshop this year, instead of before the workshop. All papers will be candidates for publishing by Springer. See instructions for camera ready copy.

Focus of Business Object Component Workshop VI

The NCITS Accredited Standards Committee H7 Object Information Management, now part of NCITS T3 Open Distributed Processing, and the Object Management Group Business Object Domain Task Force (BODTF) will jointly sponsor the Sixth Annual OOPSLA Workshop on Business Object Component Design and Implementation.

This year's focus will be on design and implementation of business object component frameworks and architectures that support enterprise application integration. A few interesting questions are:

What is a comprehensive definition of a business object component?
Are the four layers (user, workspace, enterprise, resource) presented at the OOPSLA'98 workshop the right way to layer a business object component system? (See Herzum and Sims, 1998)
How is a business object component implemented across these layers? What are the associated artifacts? Are there different object models representing the same business object component in different layers?
What are the dependencies between business object components? How can they be plug and play given these dependencies? How can they be flexible and adaptive? How do they participate in workflow systems?
How will the emergence of a web-based distributed object computing infrastructure based on XML influence business object component architectures? In particular, is the W3C WebBroker proposal appropriate for distributed business object component computing?

Early Publication of Workshop Proceedings

The OOPSLA 2000 Business Object Workshop papers submitted by May 31, 2000, will be published as a book by Springer Verlag. Later submissions will be presented at the Workshop and are candidates for publicaton in next year's book. See instructions for camera ready copy.

Goals of OOPSLA Business Object Component Workshops

Enhance the pattern literature on the specification, design, and implementation of interoperable, plug and play, distributed Business Object components.
Clarify the design and implementation of component based systems, including systems in which workflow patterns and the REA accounting model are basic building blocks for production business systems.
Contribute to emerging architectures for Intranet/Internet/Extranet applications, particularly those applications that support enterprise application integration using business object components, object and relational databases, and XML.
Pursue issues developed in previous years workshops. Specify business object component solutions to mobile agents, process engines, and systems that exhibit emergent behavior. Cross-fertilize business object design concepts with experience from the field of complex adaptive systems.
Provide explicit experience reports on business object component systems developed and in production.

Attendance

Attendance to the workshop is limited to facilitate lively discussions and the exchange of ideas. Participation will be by invitation only, based on the organizing committee's evaluation of the submissions. Accepted participants will be notified in September 2000.

Submission to Workshop

Prospective participants are solicited to submit a 2-3 page position paper or experience report, in HTML, Word or RTF format, by e-mail to jeff.sutherland@computer.org, no later than 15 September 2000. All submissions must include the full contact information of at least one author.
Position papers will be placed on the Web for review.

Background

The OOPSLA Workshop on Business Object Design and Implementation is jointly sponsored by the Accredited Standards Committee X3H7 Object Information Management Technical Committee and the Object Management Group (OMG) Business Object Domain Task Force for the purpose of soliciting technical position papers relevant to the design and implementation of Business Object systems.

X3H7 Object Information Management

The International Standards Organization (ISO) has approved a new work item to refine and extend the current international standard Reference Model for Open Distributed Processing (RM-ODP). X3H7, the U.S. technical committee for this new international work item, is tasked with the following:

Refine the enterprise language, explicating the relationship of an enterprise specification of a system to other RM-ODP viewpoint specifications of that system, so as to enable the RM-ODP to be used for specification of object-based application architectures.
Ensure that the enterprise language together with the other viewpoint languages is suitable for the specification of a concrete application architecture to fill a specific business need.
Measure success with a demonstration of the use of the RM-ODP viewpoint languages to specify a concrete application architecture.

OMG Business Object Domain Task Force (BODTF)

The Object Management Group has chartered the BODTF to facilitate and promote:

the use of OMG distributed object technology for business systems
commonality among vertical domain task force standards
simplicity in building, using, and deploying business objects - for application developers
interoperability between independently developed business objects
the adoption n and use of common business object and application component standards

And to issue requests, evaluate responses and propose for adoption by the OMG specifications for objects, frameworks, services and architectures applicable to a wide range of businesses.
