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.

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

Autonomous Temporal Transaction Database

2021 30th Conference of Open Innovations Association FRUCT, 2021
The data amount to be handled, managed, and evaluated is enormous. Intelligent information systems need to cover not just conventional data types. The whole evolution should be addressed instead. Cloud environment offers a wide range of opportunities pointing to the scalability of the solution.

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.

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 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.

Graphically Display Database Transactions to Enhance Database Forensics

2020 8th International Symposium on Digital Forensics and Security (ISDFS), 2020
Database forensics presents a set of unique challenges and these may contribute to the reason for the lack of available tools and methods for database forensics. Yet considering the pervasiveness of databases in society, the amount of sensitive data stored within these repositories, and the number of data breaches, it is perplexing why there are not ...

Transaction management in design databases

2005
Databases are being increasing applied to support design and engineering, implemented on a backend file server and supporting shared access. A fundamental difference between traditional database management and design database management is that for most of the design process, integrity is partial.

The deductive synthesis of database transactions

ACM Transactions on Database Systems, 1993
Database programming requires knowledge of database semantics both to maintain database integrity and to explore more optimization opportunities. Automated programming of database transactions is desirable and feasible. In general, transactions use simple constructs and algorithms; specifications of database semantics are available; and transactions ...

Optimistic Transaction Processing in Deterministic Database

Journal of Computer Science and Technology, 2020
Deterministic databases can improve the performance of distributed workload by eliminating the distributed commit protocol and reducing the contention cost. Unfortunately, the current deterministic scheme does not consider the performance scalability within a single machine.
