Statistical properties of transactional databases

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 ...

Transactional Databases Hyperscaling: To Be or Not to Be?

Открытые системы. СУБД, 2023
Задача линейного масштабирования аналитических нагрузок давно решена, а вот с транзакционными все оказалось не так просто — есть определенные подвижки но нет полномасштабного решения проблемы. While linear scaling of analytic workloads has been achieved long ago,

A model of transaction blocking in databases

Performance Evaluation, 1983
Abstract A simple analytic queueing model of software resource sharing in a multiprogramming environment is presented. Implicit algebraic equations for steady state mean waiting times at the various queues are developed. These equations may be solved by simple fixed point iteration.

Proving Consistency Of Database Transactions

Fifth International Conference on Very Large Data Bases, 1979., 1979
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 ...

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.
