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

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 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.

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

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.

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.

Database transaction models

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 ...

Indexing transaction time databases

Information Sciences, 1998
Abstract To support temporal operators and to increase the efficiency of temporal queries, indexing based on temporal attributes is required. We consider a temporal database with two states: the past state contains the temporal data that has once been valid, but is not valid anymore (i.e. historical data), and the current state contains only the data

Flash-aware Database Transactions

2014
Over the past 40 years, hard disks, the traditional building block of storage systems, have become increasingly slower when compared to the other system components such as the main memory and the CPU. Hard disks face mechanical constraints that cause their I/O bandwidth to lag behind capacity growth, while the access latency has remained virtually ...

Transaction Management in Engineering Databases

1984
The assumptions and procedures of engineering design are fundamentally different from those of business applications and result in quite different needs with regard to database system requirements. One important difference is in the assumptions regarding integrity.
