Title: Nilesh N Dalvi: Innovator in Database Technologies

Introduction

Nilesh N Dalvi is a prominent inventor based in Seattle, WA (US). He has made significant contributions to the field of database technologies, holding 2 patents that showcase his innovative approach to complex data queries and optimization techniques.

Latest Patents

Dalvi's latest patents include "Robust cardinality and cost estimation for skyline operator." This invention relates to incorporating a skyline operator within a relational database engine. It utilizes novel techniques to determine the lowest cost of generating the skyline produced by the skyline operator. The database engine receives queries and associated preferences, and based on a cardinality estimate and a cost estimate, an appropriate skyline generating technique is utilized to produce a skyline representative of the received queries and its associated preferences.

Another notable patent is "Computing probabilistic answers to queries." This system supports arbitrarily complex SQL queries with 'uncertain' predicates. The query semantics are based on a probabilistic model, and the results are ranked based on their probability, similar to Information Retrieval. An optimization algorithm is employed to efficiently compute most queries, determining whether a proposed plan is safe for correctly evaluating the query. In cases where a safe plan may not exist, either a 'least unsafe plan' or a Monte-Carlo simulation algorithm can be employed to produce results with acceptable error margins.
