Database transaction models

Computer Science Today, 1995
The transaction concept provides a central paradigm for correctly synchronizing concurrent activities and for achieving reliability in database systems. In transaction modeling and processing, theory and practice influence each other a lot, and over the years the transaction concept has undergone a considerable evolution from a pure implementation ...

Statistical properties of transactional databases [PDF]

Proceedings of the 2004 ACM symposium on Applied computing, 2004
Most of the complexity of common data mining tasks is due to the unknown amount of information contained in the data being mined. The more patterns and corelations are contained in such data, the more resources are needed to extract them. This is confirmed by the fact that in general there is not a single best algorithm for a given data mining task on ...

Transaction optimization in rule databases

Proceedings of IEEE International Workshop on Research Issues in Data Engineering: Active Databases Systems, 2002
The authors propose an approach to transection optimization in rule databases. It is based on a new technique to express updates in rule languages based on a non-immediate update execution. This technique is used to statically characterize some properties of the rules and transactions.

A transaction logic for database specification

ACM SIGMOD Record, 1988
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.

Testing database transactions with AGENDA

Proceedings of the 27th international conference on Software engineering - ICSE '05, 2005
AGENDA is a tool set for testing relational database applications. An earlier prototype was targeted to applications consisting of a single query and included components for populating a database with data suitable for testing the application, generating inputs to the query, and checking relatively simple aspects of the results of executing the query ...

Proving Consistency Of Database Transactions

Fifth International Conference on Very Large Data Bases, 1979., 2005
The purpose of this paper is to present an approach for verifying that explicitely stated integrity constraints are not violated by certain transactions. We utilize a relational model where-in constraints are given in a language based on the first order predicate calculus.

Transactions on the Logical Database

2014
The database as seen by an application programmer is called the logical database. In most cases the logical database is a relational database, so that application programs operate on tuples in relations through an SQL interface. A transaction is a sequence of read and update actions on the logical database, performed on the database upon a sequence of ...
