Abstract
In the Heraclitus paradigm, a delta value or more simply, delta, is a concrete value that corresponds to a difference between database states. This paper presents the Heraclitus [OO] (abbreviated H2O) DBPL, which provides a syntax and semantics for working with deltas in the context of object-oriented databases.The paper also considers the use of deltas in connection with detecting conflict between pairs of proposed updates to a database. This is useful in contexts where multiple users are each creating and choosing between multiple possible updates. A semantically based notion of potential conflict between proposed updates is developed, along with several conservative approximations based on the use of different kinds of delta.
