Traditionally, query processing gets a query and a database instance as input and returns the result of the query for that particular database instance. Reverse query processing (...
We study the scalable management of XML data in P2P networks based on distributed hash tables (DHTs). We identify performance limitations in this context, and propose an array of t...
The continuous intersection join query is computationally expensive yet important for various applications on moving objects. No previous study has particularly addressed this que...

Location-aware environments are characterized by a large number of objects and a large number of continuous queries. Both the objects and continuous queries may change their locati...
This paper tackles a major privacy concern in current location-based services where users have to continuously report their locations to the database server in order to obtain the ...
Spatio-temporal data streams that are generated from mobile stream sources (e.g., mobile sensors) experience similar environmental conditions that result in distinct phenomena. Sev...
This paper introduces an efficient algorithm for Producing Early Results in Multi-join query plans (PermJoin, for short). While most previous research focuses only on the
case of ...
