Welcome to the second International Workshop on Data Engineering Issues in E-Commerce and Services (DEECS 2006) in conjunction with the 8th IEEE Conference on E-Commerce Technology and the third IEEE Conference on Enterprise Computing, E-Commerce and E-Services. The purpose of the DEECS workshop is to provide an annual forum for exchange of state-of-the-art research and development in e-commerce and services. Since the increasing demand on e-commerce and services, we are witnessing a continuing growth of interest in the workshop. The increased number of submissions this year includes a record number from Asia. We received 47 papers: 6 from North/South America, 9 from Europe, and 32 from Asia. Of these, 15 regular papers and 8 short papers were accepted. The technical program reflects an increasing development of principles in service engineering, service-oriented architecture, data and knowledge engineering, and business models and analysis. It also reflects an increased emphasis on system and tool implementation, and applications to service practices, evidencing a maturation of the underlying principles.
