The HADAS group is part of LIG (Laboratoire d'Informatique de Grenoble). It has been known for years for its work on database systems. It has contributed in the following areas: relational data models, snapshots and their semantics, active and temporal databases and object-oriented database systems. Results of our research have direct impact on applications dealing with huge amounts of data and resources largely distributed in pervasive environments, such as data spaces, e-science, hardware, software and firmware observation, autonomic systems, and the Semantic Web.

The current activities of the group focus on the following themes:

-Accessing data in large-scale systems
-Composing data services in a dynamic way
-Reasoning on data semantics
