Abstract
Modern approaches to integrity monitoring suggest to generate triggers from constraints as part of database design and to utilize constraint simplification techniques for trigger optimization. In this paper, we show how to derive triggers from dynamic integrity constraints which describe properties of state transitions or state sequences and which can be specified by formulae in temporal logic. Such constraints can equivalently be transformed into transition graphs which describe such life cycles of database objects that are admissible with respect to the constraints. If object situations are stored, integrity maintaining triggers can be generated from transition graphs for all situations and all critical database operations. Additionally, new simplification techniques can be developed by identifying characteristic preconditions in the graphs and by utilizing invariants under database operations.
