Research Work

My research focuses on Information Integration among Heterogeneous and Autonomous Applications: It is an application driven database research, to better support the information management needs and requirements of advanced and emerging applications.
One main aim is to address the design and development of a generic system to support information sharing among a wide variety of applications, and to assist their proper collaborative working environment, and flexible information integration.
Based on the expertise gained in the design and development of the various R&D projects and based on the investigation, evaluation, and validation of the methodologies and systems in the area of information integration, a Generic and Flexible e-Science Database Integration system (e-DBI) is being designed and developed. e-DBI aims at supporting a wide variety of existing applications with efficient means for their interconnection and interoperation, while preserving their heterogeneity, distribution, and full autonomy.

Heterogeneity refers to the fact that each database may apply its own distinct DBMS, and data representation is heterogeneous in terms of structures and semantics.
Distribution refers to the storage and processing of information from distributed data sources, located on different host computers.
Autonomy refers to the fact that each database within the federation community is an independent database system. Typically, a local database is pre-existing to the creation of a cooperation network and has its own administration policies, and users community.

The following multi-disciplinary subjects are also considered within my research and development:

PLIER: Provenance Layer Infrastructure for e-Science Resources
Descriptive attributes (metadata) to grid resource files
Scientific Workflow data provenance and data annotation
Bio-banking, etc.
