Abstract. In this paper we present new concurrent and recoverable B-link-tree algorithms. Unlike previous algorithms, ours maintain the balance of the B-link tree at all times, so ...

This paper presents general algorithms for concurrency control in tree-based access methods as well as a recovery protocol and a mechanism for ensuring repeatable read. The algori...
AVL trees with relaxed balance were introduced with the aim of improving runtime performance by allowing a greater degree of concurrency. This is obtained by uncoupling updating f...
We report on initial experiments in tree locking schemes for compiled database applications. Such applications have a repository style of architecture in which a collection of sof...
The interaction history of a document can be modelled as a tree of command objects. This model does not only support recovery (undo/redo), but is also suitable for cooperation betw...
