Requirements for real-time object-oriented database models - How much is too much?

Presents an analysis of requirements for real-time object-oriented database models. The analysis is based on the assumption that in the future, real-time databases will need real-time, object-oriented, distributed, and active database features. We consider the problem of real-time object-oriented database model requirements in three steps. First, we list the aspects that we find important on real-time, object-orientation, distribution and rule handling. Second, we give a set of features of all of the aspects that should constitute the very core of a real-time object-oriented database model. Finally, we give an extended set of features that represents useful extra functionality to the models.
