Abstract

This paper presents a concurrency control algorithm for nested transactions accessing B-trees. It combines the idea of B-link tree with that of resilient 2-phase locking [Mos85b]. The I/O automaton model is used in the specification and proofs of correctness of the system. We define “strongly-serially correct” schedules and use this property as our correctness criterion.
