Sinossi
Excerpt from A Semantic Approach to Correctness, of Concurrent Transaction Executions
A natural and intuitive way to define correctness is by requiring elimination of all three types of anomalies. This approach was taken in [cars 83] and is also taken in this paper. However, the notion of serializability was assumed to be a formal counterpart of correctness by many researchers ([bern [esw [papa [sehl [ull It was pointed out by several researchers ([casa [cars [fisc [kung [schl that serializability is a too restricted notion and that meaningful results can be obtained for designing schedules which are correct but not necessarily serializable.

Paperback. Condizione: New. Print on Demand. This book explores the critical but enigmatic issue of "correctness". Correctness in this context refers to the desired behavior of multiple independent operations or entities working simultaneously. The author introduces a new and valuable concept â" "independence" â" as a key component of correctness. They posit that a system can still be considered correct even without adhering to serializability, provided it is independent. The book makes a remarkable contribution by proposing a new class of correct schedules that are neither serializable nor incorrect. This class, dubbed weakly serializable of order 2, strikes a balance between correctness and the constraint of serializability. The author's in-depth investigation of semantic constraints and integrity conditions provides a comprehensive framework for evaluating correctness, thereby significantly enhancing our understanding of this multifaceted concept. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
