Partial periodicity search, i.e., search for partial periodic patterns in time-series databases, is an interesting data mining problem. Previous studies on periodicity search mainly consider finding full periodic patterns, where every point in time contributes (precisely or approximately) to the periodicity. However, partial periodicity is very common in practice since it is more likely that on...

In this paper, we overview the PLACE server (Pervasive Location-Aware Computing Environments); a scalable location-aware database server developed at Purdue University. The PLACE server extends data streaming management systems to support location-aware environments. Location-aware environments are characterized by the large number of continuous spatio-temporal queries and the infinite nature o...

over from Erich Neuhold in 2007. I have had the pleasure of working with an oustanding TCDE Executive Committee comprised of Calton Pu, Thomas Risse, Erich Neuhold, Guy Lohman, Karl Aberer, Masaru Kitsuregawa, David Lomet and Yannis Ioannides. TCDE has continued to sponsor several conferences and workshops related to data engineering. Our flagship conference, the International Conference on Dat...

The Fourth International Workshop on Self-Managing Database Systems took place on March 29th, 2009 in Shanghai, China, on the day before ICDE. The SMDB workshops bring together researchers and practitioners interested in making data management systems easier to deploy and operate effectively. Topics of interest range from “traditional” management issues, such as database physical design, system...

Work ows are composite activities that achieve interoperation of a variety of system and human tasks. Work ows must satisfy subtle domain-speci c integrity and organizational requirements. Consequently, exibility in execution is crucial. A promising means to achieve exibility is through declarative speci cations (Part 1) with automatic distributed scheduling techniques (Part 2). We address the ...
