Title: Beng Kiong Cheah: Database Management and Performance Evaluation Innovations.

Introduction. Beng Kiong Cheah is an inventor based in Bukit Mertajam, Malaysia. His work focuses on database management, data retention, and techniques for evaluating database performance. He is associated with Dell Products Inc. and holds 2 patents.

Latest Patents. Cheah’s recent patent work addresses two challenges in database systems.

“Data retention management based on consistency of table growth and data purging activity” describes a method for tracking changes in database table size and predicting future size with a regression model. The system evaluates prediction errors to characterize table growth consistency, assesses the consistency of data-purging activity, and uses both assessments to generate data-retention recommendations. It can also initiate automated actions based on those recommendations.

“Database index evaluation using processor-based quantile classification” presents a way to prioritize database indexes using query performance data. The method can consider query execution frequency, resource-use criteria, and estimated execution-time savings associated with an index. It assigns index priorities through quantile classification and can initiate automated actions based on those priorities. The approach may compare query execution time before and after an index is implemented.

Career Highlights. Cheah’s patent portfolio reflects an emphasis on applying data analysis and automated decision-making to database operations. His inventions address both the management of data over time and the evaluation of indexes that can affect query performance.

Collaborations. Cheah is associated with Dell Products Inc. His listed coworkers include Lead Ta Choo and Tai Ee Ooi.

Conclusion. Beng Kiong Cheah’s patented work focuses on practical database innovations that support data-retention decisions and more informed index evaluation.
