Current transaction systems for geo-distributed datastores either have high transaction processing latencies or are unable to support general transactions with dependent operations. In this paper, we introduce CrossStitch, an efficient transaction processing framework that reduces latency by restructuring each transaction into a chain of state transitions, where each state consists of a key ope...

Aiming at solving the problems in the mobile computing environment such as low bandwidth, frequent disconnection and low battery capacity, we propose an improved optimistic transaction processing method -the virtual time optimistic transaction processing protocol. This protocol improves the performance of optimistic transaction processing by extending the concept of committability or, more spec...

Having been involved in the development of over two hundred small computer systems that could be classified as ‘transaction processing systems’ the author noted that, among an amazingly wide variety of applications, a relatively small number of design elements recur. These standard solutions to commonly occurring problems encountered in the development of transaction processing systems may be t...

Active and real-time databases (ARTDB) have a variety of applications in electronic brokerages in ®nancial markets, stock trading, network management and manufacturing process control. Transaction processing (TP) in ARTDB is extremely complicated since transactions may trigger other real-time transactions to an arbitrary depth with various types of dependencies (coupling modes). Therefore, tran...

Advances in wireless network technologies provide the basis for mobile computing. The wireless communication provides users with the ability to work while moving. However, mobile computing poses many constraints like frequent disconnections, low bandwidth and limited battery life, small memory etc. These constraints make mobile transaction processing environment different than centralize or dis...

Transaction management is an essential component of database management systems. It enables multiple users to access the database concurrently while preserving transactional properties such as atomicity, consistency, isolation, and durability. In this paper, we propose a formal framework specification for transaction processing. Our work can be seen as an extension of previous work by Gurevich ...

Mobile devices that host embedded database systems are becoming a commonality. Transaction management is needed to provide mobile data availability and transaction processing functionality during disconnection periods. In this paper, we present an adaptation of the transaction correctness criterion GSI to mobile networks that reduces the number of message exchanged per transaction. We discuss t...
