N2 - Recently object-oriented database technology has started to gain the attention of researchers in real-time database systems. This paper investigates major issues in designing semantic-based concurrency control for object-orient database systems supporting real-time applications, and describes an approach to solving those problems in an efficient way. This approach depends on the notion of affected-set of operations to determine operation compatibilities, and employs concurrency control algorithms augmented with priority-based conflict resolution schemes. With this method, it is impossible to manoeuvre the trade-off between logical and temporal consistency constraints in determining operation compatibilities, because the method deals with the two separately in different dimensions. However, this approach significantly lessens the complexity of the compatibility relation construction process, and can easily apply results from previous research on semantic-based concurrency control for object-oriented databases and on priority-based concurrency control for real-time database systems.
