摘要

In this paper, we take an engineering approach to atomic transaction211u001everification. We discuss the design and implementation of a verification tool 211u001ethat can reason about the semantics of atomic database operations. To bridge the 211u001egap between language design and automated reasoning, we make use of a simple 211u001emodel of objects that imitates the type-tagged memory structure of an 211u001eimplementation. This simple model is sufficient to describe the operational 211u001esemantics of the typical features of an object-oriented database programming 211u001elanguage, such as bounded iteration, heterogeneity, object creation, and nil 211u001evalues. The same model lends itself to automated reasoning with a theorem prover 211u001esystem. We are thus able to apply theorem prover technology to verification 211u001eproblems that address transaction semantics. The work has applications in the 211u001eareas of transaction safety, semantics-based concurrency control, and cooperative 211u001ework. The approach is illustrated by a graph editing example, with heterogeneous 211u001enode structures.
