A transaction logic for database specification [PDF]
We introduce a logical formalism for the specification of the dynamic behavior of databases. The evolution of databases is characterized by both the dynamic integrity constraints which describe the properties of state transitions and the transactions whose executions lead to state transitions.

Transaction reordering in replicated databases [PDF]
The paper presents a fault tolerant lazy replication protocol that ensures 1-copy serializability at a relatively low cost. Unlike eager replication approaches, our protocol enables local transaction execution and does not lead to any deadlock situation.

Testing database transaction concurrency [PDF]
Database application programs are often designed to be executed concurrently by many users. By grouping related database queries into transactions, DBMS (database management system) can guarantee that each transaction satisfies the well-known ACID properties: atomicity, consistency, isolation, and durability.

Stress Testing of Transactional Database Systems
Transactional database management systems (DBMS) have been successful at supporting traditional transaction processing workloads. However, web-based applications that tend to generate huge numbers of concurrent business operations are pushing DBMS performance over their limits, thus threatening overall system availability.

Anonymizing transaction databases for publication [PDF]
This paper considers the problem of publishing "transaction data" for research purposes. Each transaction is an arbitrary set of items chosen from a large universe. Detailed transaction data provides an electronic image of one's life. This has two implications. One, transaction data are excellent candidates for data mining research.

Optimizing transaction data performance in database management systems
One indicator of the quality of an information system is the speed of data processing. A database's most common data processing operations are adding, displaying, changing, and deleting data.
