Even though considerable research has been done on concurrency control protocols that take the timing constraints of transactions into account, most of these protocols do not predict { before a transaction begins execution { whether the transaction will meet its deadline. Hence the protocols do not directly tackle the problems introduced by the various sources of unpredictability encountered in...

Transactional memory ensures the atomicity and isolation of transactions. Although these properties greatly simplify reasoning about concurrent programs, they prevent concurrent transactions from interacting with each other. In this paper, we propose a synchronizer mechanism for augmenting software transactional memory implementations to allow different transactions to communicate with each oth...

Compensation is the process b y which a committed transaction in a database is undone b y running the semantic inverse o f that transaction on the database. Compensation has been proposed as a technique for undoing committed work in various situations where strict atomicity cannot be maintained [GS87, MR91]. In this paper, we discuss compensation i n longrunning multidatabase transactions. W e ...

A transaction-based recommender system (TBRS) aims to predict the next item by modeling dependencies in transactional data. Generally, two kinds of considered are intra-transaction dependence and inter-transaction dependence. Most existing TBRSs recommend only within current transaction while ignoring with recent transactions that may also affect item. However, as not all relevant items, ones s...
