Computing technology is combined with the development of wireless communication technology and makes a new computing model a mobile computing has become a reality.In mobile computing mode, also including database technology, the computer research work has brought new challenges.In order to effectively eliminate the mobile computing environment adverse effect brought by the access to information...

In this paper, we show that there is scope for replication in data-shipping client-server DBMSs offering opportunities for improved transactionresponse times. To support this replication, we describe a two-stage protocol for transaction processing (2STP). We extend the conventional clientserver data-shipping mechanism by allowing clients to update and query cached objects that have replicas in ...

Five years ago I proposed a common database approach for transaction processing and analytical systems using a columnar in-memory database, disputing the common belief that column stores are not suitable for transactional workloads. Today, the concept has been widely adopted in academia and industry and it is proven that it is feasible to run analytical queries on large data sets directly on a ...

First-generation streaming systems did not pay much attention to state management via ACID transactions (e.g., [3, 4]). S-Store is a data management system that combines OLTP transactions with stream processing. To create S-Store, we begin with H-Store, a main-memory transaction processing engine, and add primitives to support streaming. This includes triggers and transaction workflows to imple...

The transaction concept in computing goes back to the early days of computerized data processing. It has developed and evolved over the years both in terms of formal theory and practical application. This evolutionary process has been driven in large part by applications that require transactionlike properties. Newly emerging applications include several that involve people in a time-dependent ...

There is a need for transactional processing in the Web service world. Software industry responded to this need by publishing a couple of Web service transaction proposals that are quite alike. However, these proposals define basically only communication protocols that indirectly implement advanced transaction models. The proposals lack accurate usage suggestions and the rather obvious question...

This paper provides a comparative analysis of five implementations of transaction support. The first of the methods is the traditional approach of implementing transaction processing within a data manager on top of a read optimized file system. The second also assumes a traditional file system but embeds transaction support inside the file system. The third model considers a traditional data ma...

Flash SSDs are being incorporated in many enterprise storage platforms recently and expected to play a notable role for IOintensive applications. However, the IO characteristics of flash SSDs are very different from those of hard disks. Since existent storage subsystems are designed on the basis of characteristics of hard disks, the IO performance of flash SSDs may not be obtained as expected. ...
