This book constitutes the refereed proceedings of the Second International Workshop on Data Engineering Issues in E-Commerce and Services, DEECS 2006 held in San Francisco, California, June 2006. The book presents 15 revised full papers and 8 revised short papers organized in topical sections on e-commerce services, business processes and services, data and knowledge engineering, business models and analysis, Web services, and e-commerce systems.

This book covers recent advances in electronic commerce research activities. It aims to encourage activities in this field, and to serve researchers with an interest in electronic commerce. This book is edited from some aspects of e-commerce researches including theoretical mechanism design of trading based on auctions, allocation mechanism based on negotiation among multi-agent, case-study and analysis of e-trading, data engineering issues in e-commerce, and so on.

It is our pleasure to welcome you to the proceedings of the 13th International C- puter Society of Iran Computer Conference (CSICC-2008). The conference has been held annually since 1995, except for 1998, when it transitioned from a year-end to first-quarter schedule. It has been moving in the direction of greater selectivity (see Fig.1) and broader international participation. Holding it in Kish Island this year represents an effort to further facilitate and encourage international contributions. We feel privileged to participate in further advancing this strong technical tradition. 60 50 40 30 20 10 0 Dec 23-26 Dec 23-25 Dec 23-25 Jan 26-28 Mar 8-10 Feb 21-23 Feb 28-30 Feb 23-26 Feb 16-19 Feb 15-18 Jan 24-26 Feb 20-22 Mar 9-11 1995 1996 1997 Iran 1999 2000 2001 U of 2002 Iran 2003 2004 2005 Iran 2006 IPM, 2007 2008 Sharif U Amirkabir U of Sharif U Shahid Isfahan, Telecom Ferdowsi Sharif U Telecom Tehran Shahid Sharif U of Tech, U of Tech, Sci/Tech, of Tech, Beheshti Isfahan Res.

The e-business environment presents a variety of challenging data engineering problems, such as product information management and ontological support for e-business. DEEC 2005 presents and discusses ideas on data engineering issues in this dynamic environment. This Workshop is presented in four parts: ontologies in e-Commerce, e-Commerce contents and standards, Web Services for database applications, and e-Commerce frameworks and supporting technologies. The selection of papers clearly indicates the breadth of contributions across the field of E-Commerce.

This volume contains the final proceedings of the special stream on security in E-government and E-business. This stream has been an integral part of the IFIP World Computer Congress 2002, that has taken place from 26-29 August 2002 in Montreal, Canada. The stream consisted of three events: one tutorial and two workshops. The tutorial was devoted to the theme "An Architecture for Information Se curity Management", and was presented by Prof. Dr. Basie von Solms (Past chairman of IFIP TC 11) and Prof. Dr. Jan Eloff (Past chairman of IFIP TC 11 WG 11.2). Both are from Rand Afrikaans University -Standard Bank Academy for Information Technology, Johannesburg, South Africa. The main purpose of the tutorial was to present and discuss an Architecture for Informa tion Security Management and was specifically of value for people involved in, or who wanted to find out more about the management of information secu rity in a company. It provided a reference framework covering all three of the relevant levels or dimensions of Information Security Management. The theme of the first workshop was "E-Government and Security" and was chaired by Leon Strous, CISA (De Nederlandsche Bank NY, The Netherlands and chairman of IFIP TC 11) and by Sabina Posadziejewski, I.S.P., MBA (Al berta Innovation and Science, Edmonton, Canada).

This book constitutes the refereed proceedings of the 25th International Conference on Conceptual Modeling, ER 2006, held in Tucson, AZ, USA in November 2006. The 37 revised full papers presented together with two keynote talks, two panel session papers, six industrial papers, and five demo/posters papers were carefully reviewed and selected from 158 submissions.
