It does not advance the state of the art, although it does provide a simple framework for expressing what we already know. It is well written and can be easily comprehended by anyone with some background in computer science or database management systems. The paper also has some useful and educational information on the challenges facing transaction recovery and concurrency control. They also classify various commercial database management systems, including Ingres, System/R, and R*. For each instance, the authors describe various challenges in terms of transaction recovery, concurrency control, and coordination in distributed environments. The authors identify several interesting instances of this model (or the classification scheme). The above five attributes form a model for classification of transaction processing systems.

The authors identify five quantitative attributes of database management systems: number of sites, number of machines, number of processes (executing software entities), degree of heterogeneity in the machines and system software, and number of logical data schemata. The problems are related to recovery, concurrency, and coordination. The authors put forward the notion that the problems in building transaction processing systems are a function of the pivotal attributes of the underlying database management systems.
