Distributed database processing requires the transmission of data between computers in a distributed system. Data transmission is becoming an increasingly attractive data-dissemination method for large database systems. In order to effectively utilize distributed query processing, it is necessary to have efficient dynamic allocation algorithms that can balance individual and overall performance...

'Advanced database applications', such as CAD/CAM, CASE, large AI applications or image and voice processing, place demands on transaction management which differ substantially from those in traditional database applications. In particular, there is a need to support 'enriched' data models (which include, for example, complex objects or version and configuration management), 'synergistic' coope...

We introduce different mobile network applications and show to which degree the concept of database transactions is required within the applications. We show properties of transaction processing and explain which properties are important for each of the mobile applications. Furthermore, we discuss open questions regarding transaction processing in mobile networks and identify open problems for ...

Market-based principles can be used to manage the risk of distributed peer-to-peer transactions. This is demonstrated by Ptrim, a system that builds a transaction default market on top of a main transaction processing system, within which peers offer to underwrite the transaction risk for a slight increase in the transaction cost. The insurance cost, determined through market-based mechanisms, ...

This paper describes operational aspects of a novel approach to active rule processing based on a transaction transformation technique. A user deened transaction , which is viewed here as a sequence of atomic database updates forming a semantic unit, is translated by means of active rules into a new transaction that explicitly includes the additional updates due to active rule processing. It fo...

Autonomous multidatabases, Computer Aided Design (CAD) databases, and Object Oriented Databases have requirements that cODstitute a few examples of systems where traditional transactions may not be sufficient. Users of these advanced applications are more sophisticated than users envisioned for On Line Transaction Processing (OLTP) applications a few decades ago. The need to relax the propertie...

Typical transactions of online transaction processing (OLTP) workloads have large instruction footprints, 128KB-1MB, that cannot fit in existing L1-I caches, 32KB [1]. Extensive capacity misses due to instructions lead to severe under-utilization of modern hardware’s micro-architectural resources [3]. As opposed to the traditional way where a transaction starts and completes its execution on a ...

In this paper, we present a study on the concurrency control and recovery algorithms in nested transaction environment. We have reviewed the work done in the area of nested transaction modelling, its applications in object-oriented and mobile databases, and in workflow models. We have contrasted various nested transaction models by discussing their advantages and disadvantages. We have outlined...

RelaX offers an extensible transaction facility which isolates distributed (thus complex) transaction processing. A distributed system providing basic support for local recovery may easily be enhanced with flexible transaction functionality by linking it to the RelaX facility. The work desribed is being carried out in conjunction with the European ESPRIT Comandos project. In the Comandos platfo...
