RESEARCH AREA: Object-oriented databases

Both data modelling and architectural issues have been investigated. Specifically, the research activities on this topic include:

• Formalization and extensions of object-oriented data models (most notably, with composite objects)
• Set-oriented execution of object updates and methods
• View mechanisms for object-oriented data models
• Deductive, active, and temporal extensions of the object-oriented data model
• Index structures
