In order to establish a theoretical foundation for database transformations, we search for a universal computation model as an umbrella for queries and updates. As updates are fundamentally distinct from queries in many respects, computation models for queries cannot be simply extended to database transformations. This motivates the question whether Abstract State Machines (ASMs) can be used to characterise database transformations in general. In this paper we start examining the differences...[Show more]
