The rapid development and prevalent use of the Web highlight the requirement for new technologies for design, implementation and management of Web-based information systems. It is evident that distributed, heterogeneous data increasingly found on the Web introduces new challenges beyond the capability of traditional database systems. With this comes the need for Web-based information systems, which are to provide effective and efficient techniques for specifying, retrieving, integrating, exchanging, querying, archiving, managing, analyzing, cleaning and securing the data on the Web. The application of Web-based information systems calls for seamless integration of technologies from database systems and Internet management, and is essential to the development of Web services, e-commerce and e-science, among other things.

WAIM is a leading international conference for researchers, practitioners, developers, and users to share and exchange ideas, results, experience, techniques, and tools in connection with all aspects of Web data management. As the 13th event in the increasingly popular series, WAIM 2012 expects to attract participants from all over the world to Harbin, China, and continues to establish WAIM as one of the major conferences on Web-based information systems.
