A Formal Model for the Problem of View Selection for Aggregate Queries
We present a formal analysis of the following view-selection problem: Given a set of queries and a database, return definitions of views that, when materialized in the database, w...

Exact aggregate solutions for M/G/1-type Markov processes
We introduce a new methodology for the exact analysis of M/G/1-type Markov processes. The methodology uses basic, well-known results for Markov chains by exploiting the structure ...
