Query-Driven Data Allocation Algorithms for Distributed Database Systems
We develop a site-independent fragment dependency graph representation to model the dependencies among the fragments accessed by a query, and use it to formulate and solve data allocation problems for distributed database systems based on query-site and move-small query execution strategies. Expand
