This book constitutes the refereed combined proceedings of four international workshops held in conjunction with the joint 9th Asia-Pacific Web Conference, APWeb 2007, and the 8th International Conference on Web-Age Information Management, WAIM 2007, held in Huang Shan, China in June 2007 (see LNCS 4505).

The 50 revised full papers and 25 revised short papers presented together with the abstract of 1 keynote talk were carefully reviewed and selected from a total of 266 submissions. The papers of the four workshops are very specific and contribute to enlarging the spectrum of the more general topics treated in the APWeb 2007 and WAIM 2007 main conferences. Topics addressed by the workshops are: Database Management and Application over Networks (DBMAN 2007), Emerging Trends of Web Technologies and Applications (WebETrends 2007), Process Aware Information Systems (PAIS 2007), and Application and Security Service in Web and Pervasive Environments (ASWAN 2007).
