Download or read book Associative Caching in Client server Databases written by Julie Basu and published by . This book was released on 1998 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: We first describe the architecture of A*Cache and its transaction execution model. We then develop new optimization techniques for improving the performance of A*Cache. Next, A*Cache performance is investigated through detailed simulation of a client-server database under many different workloads, and compared with other types of caching systems. The simulation results clearly demonstrate the effectiveness of our associative caching scheme for read-only environments, and also for read-write scenarios with moderately high data update probabilities.
Download or read book Performance Analysis of an Associative Caching Scheme for Client Server Databases written by Stanford University. Computer Science Department and published by . This book was released on 1997 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a detailed performance study of the associative caching scheme proposed in "A Predicate-based Caching Scheme for Client-Server Database Architectures," The VLDB Journal, Jan 1996. A client cache dynamically loads query results in the course of transaction execution, and formulates a description of its current contents. Predicate-based reasoning is used on the cache description to examine and maintain the cache. The benefits of the scheme include local evaluation of associative queries, at the cost of maintaining the cached query results through update notifications >From the server. In this paper, we investigate through detailed simulation the behavior of this caching scheme for a client-server database under different workloads and contention profiles. An optimized version of our basic caching scheme is also proposed and studied. We examine both read-only and update transactions, with the effect of updates on the caching performance as our primary focus. Using an extended version of a standard database benchmark, we identify scenarios where these caching schemes improve the system performance and scalability, as compared to systems without client-side caching. Our results demonstrate that associative caching can be beneficial even for moderately high update activity.
Download or read book Caching and Materialization for Web Databases written by Alexandros Labrinidis and published by Now Publishers Inc. This book was released on 2010-02-19 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Database systems have been driving dynamic web sites since the early 90s; nowadays, even seemingly static web sites employ a database back-end for personalization and advertising purposes. In order to keep up with the high demand fuelled by the rapid growth of the Internet, a number of caching and materialization techniques have been proposed for web databases over the years. The main goal of these techniques is to improve performance, scalability, and manageability of database-driven dynamic web sites, in a way that the quality of data is not compromised. Although caching and materialization are well understood concepts in the traditional database and networking/operating systems literature, the Web and web databases bring forth unique characteristics that warrant new techniques and approaches. In this survey, we adopt a data management point of view to describe the system architectures of web databases, and analyze the research issues related to caching and materialization in such architectures. We also present the state of the art in caching and materialization for web databases and organize current approaches according to the fundamental questions, namely how to store, how to use, and how to maintain cached/materialized web data. Finally, we associate work in caching and materialization for web databases to similar techniques in other related areas, such as data warehousing, distributed systems, and distributed databases.

Book excerpt: The Database and Expert Systems Applications (DEXA) conferences have established themselves as a platform for bringing together researchers and practitioners from various backgrounds and all regions of the world to exchange ideas, experiences and opinions in a friendly and stimulating environment. The papers presented at the conference represent recent developments in the field and important steps towards shaping the future of applied computer science and information systems. DEXA covers a broad field: all aspects of databases, knowledge based systems, knowledge management, web-based systems, information systems, related technologies and their applications. Once again there were a good number of submissions: out of 183 papers that were submitted, the program committee selected 92 to be presented. In the first year of this new millennium DEXA has come back to the United Kingdom, following events in Vienna, Berlin, Valencia, Prague, Athens, London, Zurich, Toulouse, Vienna and Florence. The past decade has seen several revolutionary developments, one of which was the explosion of Internet-related applications in the areas covered by DEXA, developments in which DEXA has played a role and in which DEXA will continue to play a role in its second decade, starting with this conference.

Book excerpt: Getting data across platforms and formats is a cornerstone of present-day applications development. ADO: ActiveX Data Objects is both an introduction and a complete reference to ADO (ActiveX Data Objects), Microsoft's universal data access solution. You'll learn how to easily access data in multiple formats--such as email messages, Access databases, Word documents, and SQL databases--even on different platforms, without spending extra time learning every last detail about each format. Author Jason Roff shows by example how to use ADO with your programming language of choice to save programming time, so you can concentrate on the content and quality of your application rather than the nitty-gritty of specific data formats. ADO: ActiveX Data Objects includes: Chapters dedicated to the Connection, Recordset, Field, and Command objects and the Properties collection A complete, detailed reference listing every ADO object, method, property, and event, in convenient alphabetical order Chapters on ADO architecture, data shaping, the ADO Event Model An appendix containing enumeration tables used by ADO objects and collections, listed alphabetically Brief introductions to RDS, ADO.NET, and SQLADO: ActiveX Data Objects is a versatile one-stop guide to both the theory and practice of programming with ADO through Version 2.6. The thorough reference section and topic-specific chapters will help you find quick answers about the details of objects, collections, methods, and properties of ADO. And the abundance of practical code examples will give you a good grasp of how to use ADO's strong points most effectively.
