Transaction Models and Transaction Management in Object-Oriented Database Management Systems

Abstract

Transactions are important primitives to provide reliability and controlled access to shared databases. The theory and practice of conventional transaction management involving simple read/write transactions and enforcing serializability have already been developed. In the case of object-oriented database management systems, the traditional transaction management techniques are not sufficient and more powerful transaction models and more flexible correctness criteria need to be developed. The additional complexity of these systems proves to be a significant obstacle to their development. In this paper we review both the problems and the approaches that have been proposed to tackle these problems.
