In this work, we focus on managing scientific environmental data, which are measurement readings collected from wireless sensors. In environmental science applications, raw sensor...
We consider the class of database programs and address the problem of minimizing the cost of their exchanges with the database server. This cost partly consists of query execution...
The problem of answering queries using views is to find efficient methods of answering a query using a set of previously materialized views over the database, rather than accessin...
Structural join operations are central to evaluating queries against XML data, and are typically responsible for consuming a lion's share of the query processing time. Thus, ...
Automated physical design tuning for database systems has recently become an active area of research and development. Existing tuning tools explore the space of feasible solutions...
