Title: The Innovations of Tam Minh Dai Tran

Introduction

Tam Minh Dai Tran is a notable inventor based in San Jose, CA. He has made significant contributions to the field of data processing, holding a total of 6 patents. His work focuses on optimizing query processing in databases, which is crucial for improving data retrieval efficiency.

Latest Patents

One of his latest patents is titled "Multi-fact query processing in data processing system." This patent describes techniques for optimizing a multi-fact star schema query to retrieve data from multiple fact tables within a database. The optimization techniques involve transforming a received multi-fact star schema query into a group of single-fact sub-queries, which helps in reducing or eliminating certain constraints during query processing. The execution of these sub-queries is then planned to efficiently retrieve the necessary data.

Another significant patent is "Selectivity estimation for conjunctive predicates in the presence of partial knowledge about multivariate data distributions." This patent provides a method for consistent selectivity estimation based on the principle of maximum entropy (ME). The method effectively utilizes all available information while avoiding bias issues. When detailed knowledge is lacking, the ME approach simplifies to standard uniformity and independence assumptions. This innovative method enhances the optimizer's cardinality estimates, leading to improved plan quality and significantly reduced query execution times.
