Efficient transaction processing in SAP HANA database: the end of a column store myth

SIGMOD Conference, 2012
The SAP HANA database is the core of SAP's new data management platform. The overall goal of the SAP HANA database is to provide a generic but powerful system for different query scenarios, both transactional and analytical, on the same data ...

Transaction management in design databases

Journal of Systems and Software, 1993
Abstract Conventional data base systems are not suitable for handling advanced applications encountered in engineering, such as CAD/CAM, CASE, CAE, and VLSI design. The data bases in such environments, also called design data bases, are characterized by the presence of many complex data objects denoted by a large number of small tables, as opposed to

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.

Transaction Management in Mobile Databases

2007
Recent advances in wireless communications and computer technology have provided users the opportunity to access information and services regardless of their physical location or movement behavior. In the context of database applications, these mobile users should have the ability to both query and update public, private, and corporate databases.

A Logic for Programming Database Transactions [PDF]

, 1998
We propose an extension of classical predicate calculus, called Transaction Logic, which provides a logical foundation for the phenomenon of state changes in logic programs and databases. Transaction Logic comes with a natural model theory and a sound and complete proof theory.

Research based on database transactions

2011 IEEE 3rd International Conference on Communication Software and Networks, 2011
The process of using the database in order to ensure the correctness of data manipulation, we realized affairs. Transaction is a set of logical operation unit, the data transformation from one state to another state, to ensure consistency of data in the database, data manipulation should be discrete groups of logic cells, and when it all finished, Data

On transaction liveness in replicated databases [PDF]

Proceedings Pacific Rim International Symposium on Fault-Tolerant Systems, 2002
This paper makes a first attempt to give a precise characterisation of liveness in replicated database systems. We introduce the notion of liveness degrees, which express the expectation a database user might have about the termination of its transactions, despite concurrency and failures.

Cooperating transactions in a versioned database

[1993] Proceedings International Conference on Intelligent and Cooperative Information Systems, 2002
EPOS (Expert system for PrOgram and System development) is a kernel software engineering environment, offering integrated software configuration management (CM) and process management. The EPOS process modelling (PM) support system runs on top of the versioned EPOS database (DB), operating in client-server mode.

The End of a Myth: Distributed Transaction Can Scale

Proceedings of the VLDB Endowment, 2016
The common wisdom is that distributed transactions do not scale. But what if distributed transactions could be made scalable using the next generation of networks and a redesign of distributed databases?
