Flexible and Scalable Query Planning in Mediators

Research Statements

My research interests are on flexible and efficient query processing in mediator systems. In the context of the SIMS (Arens et al. 1993; Arens, Knoblock, and Shen 1996) and Ariadne (Knoblock et al. 1998) projects, we have applied a general framework for efficient highquality planning, called Planning by Rewriting (Ambite and Knoblock 1997), to the problem of generating query plans in distributed and heterogeneous environments (Ambite and Knoblock 1998).
