Abstract

Algorithms for the transaction rollback belong to the fundamentals of database theory and practice. Much less attention has been paid to the method rollback in the realm of object-oriented systems. This issue was studied in the context of exception handling. In a previous paper, a new algorithm for computing old attribute values has been proposed. In this paper that algorithm is used to implement a procedure for method rollback. It is shown that this procedure ensures the so called strong exception safety.
