Portrait of Liang Jeff Chen

Liang Jeff Chen



My name is Liang Chen. I am commonly referred to as Jeff in my professional career. I am a member of Cloud & Mobile Research Group. I am generally interested in data management. I’ve also worked on text search and ranking before. Most recently, I become a system researcher and build NoSQL systems that use SQL databases as core engines. The long term goal is to bridge the fundamental gap between NoSQL challenges and fast-evolving SQL technologies, so that the efforts we invest today are as long lived as SQL for many years to come.

I obtained BS and MS from Tsinghua University, and PhD from UC San Diego.

Building from scratch provides good opportunities to abandon historical burden and re-design systems with state-of-the-art wisdom. However, it also means that we have to re-build many canonical SQL technologies all over again, technologies that are products of years of research and development and are…

JSON Server – Transforming SQL Server and MariaDB to a JSON Database

JSON Server is not an independent database, but a middleware that accepts operations against JSON documents and…
