Two terminals and users, major approaches to a large volume of onperformance evaluation line data and storage are measurement and devices, and a high modeling. ...

The need for information access and processing inmobile computing environments presents great challenges to database researchers. Apart from advances in wireless communications and device technology, new data management techniques are needed to provide a transparent interaction between fixed and mobile devices in global information systems. A key aspect is to provide a flexible and powerful tra...

Many multiple server systems are now being used for heavily accessed web services. Performance, availability, and real-time transaction processing are important requirements for many of these applications. In this paper, we apply the multi-invariant data structure (MIDS) concept to develop an atomic transaction processing algorithm. We show that our algorithm achieves nonblocking property. It a...

In Digital's database addition to other database products, VAX Rdb/VMS services, KODA provides the and VAX DBMS, share the transaction capabilities same database kernel and commit processing for called KODA. KODA uses these two products. a grouping mechanism to In this paper, we address commit many concurrent some of the issues relevant transactions together. to efficient co...

Performance of transaction processing systems is mostly determined by the amount of required physical disk I/O, which is due to database table accesses or log record writes. This paper describes a high-performance transaction processing system called Charm, which aims to reduce the performance impacts of disk I/O to the minimum. In current transaction processing architectures, a transaction blo...

The performance of a transaction processing system whose database is not completely memory-resident critically depends on the amount of physical disk I/O required. This paper describes a high-performance transaction processing system called Charm, which aims to reducing the concurrency control overhead by minimizing the performance impacts of disk I/O on lock contention delay. In existing trans...

In this paper, we address a speci"c topic within the context of nested transaction implementation, namely, the assignment of identi"ers to transactions. We discuss the most important information such identi"ers should carry. We do this based on an analysis of the main requirements the components of a general transaction processing system pose on the identi"ers. Thereafter, we present some schem...

Transaction processing is of growing importance for mobile computing. Booking tickets, flight reservation, banking, ePayment, and booking holiday arrangements are just a few examples for mobile transactions. Due to temporarily disconnected situations the synchronisation and consistent transaction processing are key issues. Serializability is a too strong criteria for correctness when the semant...
