Transitive Dependencies in Transaction Closures

Complex applications consist of a large set of transactions which are interrelated. There are different kinds of dependencies among transactions of a complex application, e.g. termination or execution dependencies which are constraints on the occurrence of significant transaction events. In this paper, we analyze a set of (orthogonal) transaction dependencies. Here, we do not follow traditional approaches which consider advanced transaction structures as a certain kind of nested transactions. We introduce the notion of transaction closure as a generalization of nested transactions. A transaction closure comprises all transactions which are (transitively) initiated by one (root) transaction. By specifying dependencies among transactions of a transaction closure we are then able to define well-known transaction structures like nested transactions as well as advanced activity structures, e.g. workflows, in a common framework. In particular, we consider the transitivity property for all k...
