Applying relational algebra and RelView to coalition formation [PDF]

open access: yes
We present an application of relational algebra to coalition formation. This leads to specifications, which can be executed with the help of the RelView tool after a simple translation into the tool's programming language.

Monotonically improving approximate answers to relational algebra queries [PDF]

open access: yes
We present here a query processing method that produces approximate answers to queries posed in standard relational algebra. This method is monotone in the sense that the accuracy of the approximate result improves with the amount of time spent producing

XQ2P: Efficient XQuery P2P Time Series Processing

open access: yes, 2009
In this demonstration, we propose a model for the management of XML time series (TS), using the new XQuery 1.1 window operator. We argue that centralized computation is slow, and demonstrate XQ2P, our prototype of efficient XQuery P2P TS computation in ...
