RESEARCH PROJECTS

A Holistic Approach for Scale-Independent Query Processing

This project aims to design a holistic approach for scale-independent query processing on big data, addressing critical issues like cost-based optimization, cardinality constraints, and join optimization. The goal is to ensure efficient information retrieval regardless of data size, contributing to advancements in big-data applications' database systems.
