Database Theory and Engineering Lab

Welcome to the Database Theory and Engineering Lab (DTELab) at the Department of Computing and Software, McMaster University. The DTELab is focused on innovative database research on foundational technologies for future databases, with a strong combined focus on the intersection of theoretical and engineering challenges in the areas of data management and transaction processing.

Projects

Our current research projects focus on distributed data management (with a particular focus on resilience and trust), on graph data (with a particular focus on graph query optimization), and, in general, high-performance data management.
