This book publishes all the papers presented in the first Business object Design & Implementation Workshop which was held in OOPSLA'95 conference where there were 12 position papers presented. The theme of that workshop was largely surrounding the areas of applying Object-Oriented Analysis and Design (OOAD) methods within the business environment. [Casanave 95] proposed to integrate the Common Object Request Broker Architecture (CORBA) with the middle layer architecture and to form a standard of Business Object Architecture for vertical industry's applications. Casanave's approach was supported by [Poirier et al 95] which proposed a telecommunication architecture Business object model. [Hertha et al 95] proposed a 3-model 4-tier framework for business applications. [Kossman 95] proposed a model to support real-time OO systems. [Digre 95] proposed a component based architecture for client/server distributed applications. [Ramackers et al 95] proposed a CASE tool environment to integrate OO modelling, Business Process Reengineering (BRP) and workflow management. [Grothehen et al 95] proposed a mechanism to interface with legacy system. [McCarthy et al 95] suggested a Resource-Event-Agent (REA) for value-added processes of a business enterprise. [Schwaber 95] used the rugby metaphor by adding a SCRUM management technique in OO project. Based on the position papers presented, Business Objects were used in a wide range of spectrums in both academic and industrial sectors. Most, if not all, the presenters held high calibre in their particular industrial / academic sectors. That's how they made such a good quality paper.
