Top-N Query Processing

The objective of this project is to develop techniques for the efficient evaluation of top-N queries. A top-N query returns the N results that satisfy the query condition the best but not necessarily completely. Satisfaction of the result with respect to a query is measured by the distance between the tuple and the query based on some distance function.
