The ER 2006 organizing committee is pleased to present the following tutorials to be held with the 25th International Conference on Conceptual Modeling to be held in Tucson, Arizona, USA, between November 6-9, 2006.

• State of the Art in Modeling and Deployment of Electronic Contracts - Kamalakar Karlapalem and P. Radhakrishna. Length 3 hours.

  Electronic contracts start from being legal documents to processes that help organizations to abide by the legal rules while fulfilling the contracts. Deployment of electronic contracts poses a lot of challenges at three levels, namely conceptual, logical and implementation. Changes in the factors influencing the contract execution require changes at one or more levels. In these tutorial, basic concepts of e-contracts, modeling frameworks, deployment scenarios of e-contracts will be presented. Specific case studies from current literature and business practice will illustrate the current state of the art, and help enumerate the open research problems that need to be addressed.

   

• Conceptual Modeling for Emerging Web Application Technologies - Dirk Draheim and Gerald Weber. Length 90 minutes.

  This tutorial analyzes web application technologies in the semantically well-defined framework of form-oriented analysis. We identify the underpinnings of new web application technologies in terms of approved concepts of the modeling community. For example, a web form turns out to be an editable method call, the ubiquitous Model-2-Architecture for web applications turns out to be functional decomposition. On the basis of the viewpoint of a strict submit/response style system, the participant of this tutorial should be empowered to decide which work products are appropriate in his or her concrete project and which details of advanced technologies should actually have a footprint in the system documentation. No single solution fits all sizes - web application projects range from little web shops for a dozen of products to huge business-to-customer portals involving many CRM-related aspects. To trigger the discussion, we propose a well-defined set of documents and work-products for a standard, medium-size web application project. We give the model of an example web shop as a comprehensive example and discuss real-world case studies.

• Web Change Management and Delta Mining: Opportunities and Solutions - Sourav S Bhowmick and Sanjay Madria. Length 90 minutes.
  In this tutorial, we focus on detecting, representing and mining changes to XML data. We focus on the following aspects of this problem: Mechanism for Detecting Changes to XML Data: In practice, users often need to detect changes by comparing two or more snapshots of XML data or documents. We will discuss changes to hyperlinked structure of a set of XML documents using graph-based and relational model based approaches. I will show comparison of these two approaches using various tools available in commercial and academic domain, and their advantages and disadvantages.
