J. J. Prichard, Lisa Cingiser DiPippo, Joan Peckham, Victor Fay Wolfe
1994 Lecture Notes in Computer Science  
We have i n tegrated real-time, object-oriented, semantic and active database approaches to develop a formal model called RTSORAC for real-time databases.  ...  A real-time database is a database in which both the data and the operations upon the data may h a ve timing constraints.  ...  RTSORAC Real-Time Semantic Objects Relationships And Constraints is a real-time object-oriented database model that incorporates these concepts.  ...
