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.

This two volume set LNCS 7238 and LNCS 7239 constitutes the refereed proceedings of the 17th International Conference on Database Systems for Advanced Applications, DASFAA 2012, held in Busan, South Korea, in April 2012. The 44 revised full papers and 8 short papers presented together with 2 invited keynote papers, 8 industrial papers, 8 demo presentations, 4 tutorials and 1 panel paper were carefully reviewed and selected from a total of 159 submissions. The topics covered are query processing and optimization, data semantics, XML and semi-structured data, data mining and knowledge discovery, privacy and anonymity, data management in the Web, graphs and data mining applications, temporal and spatial data, top-k and skyline query processing, information retrieval and recommendation, indexing and search systems, cloud computing and scalability, memory-based query processing, semantic and decision support systems, social data, data mining.
