A novel strategy for the representation and manipulation of distributed documents, potentially complex and heterogeneous, is presented in this paper. The document under the propos...
— This work presents an H2 performance analysis of the agreement protocol in the presence of noise. The agreement protocol is first transformed into an equivalent system induced...
We provide an evaluation of query execution plans (QEP) in the case of queries with one or two spatial joins. The QEPs assume R -tree indexed relations and use a common set of spat...

We consider a class of routing problems on connected graphs G. Initially, each vertex v of G is occupied by a “pebble” which has a unique destination π(v) in G (so that π is...
We address the problem of finding parallel plans for SQL queries using the two-phase approach of join ordering followed by parallelization. We focus on the parallelization phase a...
