抄録
This paper presents a method of automatically determining compatibility
of method invocations in an Object-Oriented Database (OODB) based on
state-based commutativity. Semantics exploitation is one of the common
techniques of increasing concurrency in transaction processing. In OODB,
object creator defines, in a compatibility table, a semantic-based way
of how methods commute and Concurrency Control Module refers to it to
establish if two method invocations on that object can take place
concurrently. In this paper, we seek to automate this process by
establishing invocation compatibilities at transaction execution time
from the semantics of methods using a set of affected attributes
summarized in what we have called Access-Mode-Set (AMS).
