Research Areas - Database Management Systems (DBMS)

Overview

Large-scale computing services revolve around the management, distribution and analysis of massive data sets. For over 40 years, Berkeley has led the world in recognizing and advancing the centrality of data in computing. Faculty and students at Berkeley have repeatedly defined and redefined the broad database field, combining deep intellectual impact with the birth of multi-billion dollar industries, including relational databases, RAID storage, scalable Internet search and big data analytics. Berkeley also gave birth to many of the most widely-used open source systems in the field including INGRES, Postgres, BerkeleyDB and Apache Spark. Today, our research continues to push the boundaries of data-centric computing, taking the foundations of data management to a broad array of emerging scenarios.
