Invented about 40 years ago and called ubiquitous less than 10 years later, B-tree indexes
have been used in a wide variety of computing systems from handheld devices to …

We describe a methodology for transforming a large class of highly-concurrent linearizable
objects into highly-concurrent transactional objects. As long as the linearizable …

Two novel concurrency algorithms for abstract data types are presented that ensure
serializability of transactions. It is proved that both algorithms ensure a local atomicity …

One of the demands of database system transaction management is to achieve a high
degree of concurrency by taking into consideration the semantics of high-level operations …

Compensating transactions are intended to handle situations where it is required to undo
either committed or uncommitted transactions that affect other transactions, without resorting …

The concurrency of transactions executing on atomic data types can be enhanced through
the use of semantic information about operations defined on these types. Hitherto …

Mutual exclusion and coucurreucy are two fuudameutal and essentially opposite features in
distributed systems. However, in some applications such as computer supported …
