A Linear Temporal Logic Approach to Objects with Transactions

Our concern is the high level speciication of reactive software systems such as information systems. We adopt an object oriented, temporal logic based approach to speciication. The notion of transaction incorporates various application domains, for instance transactions as abstractions from processes as known from reenement theory, transactions as abstractions from business processes as known in business process modelling or database transactions. In this paper we investigate object speciications with transactions. We illustrate the use of transactions by examples given in an object oriented style and introduce a linear temporal logic with transactions (Tosl) which serves as denotional model for such object speciications with transactions. We explain how Tosl is semantically deened in terms of life cycles and illustrate by example the translation of object speciications to Tosl. Using Tosl for system speciication results in sets of formulae which are independent from the level of granularity.
