Abstract

Object-oriented database systems provide a challenge in the area of concurrency control because of the complicated types of data that exist in these databases and because of the semantic relationships that exist among the data. In particular, the class/subclass, class/instance, and aggregate object hierarchies demand richer and more complex locking protocols than exist in conventional systems. This paper provides locking protocols for transactions operating in an object-oriented environment, emphasizing the necessary steps to be taken when accessing objects semantically related to other objects via the three hierarchies.
