Book Description
This book is concerned with the architectural alternatives for client-server database systems, presenting the arguments for using caching as the basis for constructing page server database systems, and providing an overview of other environments in which caching-related issues arise. A significant amount of the text is focused on the development and simulation-based performance analysis of algorithms for data caching and memory management, including a performance study of seven proposed algorithms. Caching-based techniques to further improve system performance and scalability, and client data caching as an organizing principle for distributed information systems. This book is for anyone interested in the performance and architecture of distributed information systems, and object-based database management systems particularly.

Book Description
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.

Book Description
Despite the significant ongoing work in the development of new database systems, many of the basic architectural and performance tradeoffs involved in their design have not previously been explored in a systematic manner. The designers of the various systems have adopted a wide range of strategies in areas such as process structure, client-server interaction, concurrency control, transaction management, and memory management. This monograph investigates several fundamental aspects of the emerging generation of database systems. It describes and investigates implementation techniques to provide high performance and scalability while maintaining the transaction semantics, reliability, and availability associated with more traditional database architectures. The common theme of the techniques developed here is the exploitation of client resources through caching-based data replication. Client Data Caching: A Foundation for High Performance Object Database Systems should be a value to anyone interested in the performance and architecture of distributed information systems in general and Object-based Database Management Systems in particular. It provides useful information for designers of such systems, as well as for practitioners who need to understand the inherent tradeoffs among the architectural alternatives in order to evaluate existing systems. Furthermore, many of the issues addressed in this book are relevant to other systems beyond the ODBMS domain. Such systems include shared-disk parallel database systems, distributed file systems, and distributed virtual memory systems. The presentation is suitable for practitioners and advanced students in all of these areas, although a basic understanding of database transaction semantics and techniques is assumed.

Book Description
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 Description
Recently, client-side data caching has become popular for building highly interactive web applications. This research is about client-side data caching in a client-server OLAP system. Contrary to the traditional OLAP systems, the system we study here is client-centric which contains a light-weight OLAP engine and a data cache, such that queries posed by the user may be processed on the client without a round-trip to the server. It has been shown that this system works better than the traditional ones in some data visualization scenarios. In this study, we focus on the client-side data caching in this system. We implemented a new data structure for storing multidimensional data on the client-side, which occupies a small memory footprint and decreases the load time significantly with a minimal client-side processing overhead. Also, we investigate the efficiency of client-side caching when the processing of the query needs extra data that are not already client-resident. Our results show that in some cases it could be cost-effective to download more than 80% of the required data from the server, rather than to download the entire sub-cube from the server.

Book Description
The International Web Content Caching and Distribution Workshop (WCW) is a premiere technical meeting for researchers and practitioners interested in all aspects of content caching, distribution and delivery on the Internet. The 2001 WCW meeting was held on the Boston University Campus. Building on the successes of the five previous WCW meetings, WCW01 featured a strong technical program and record participation from leading researchers and practitioners in the field. This book consists of all the technical papers presented at WCW'01. It includes 20 full papers and four R&D synopses that were presented at the workshop. The collection reflects the latest research in this important area, including such topics as Content Delivery Networks (CDNs), tools and methodology of performance measurements, Web characterization as relates to caching and content distribution, scalable web server architectures, cache prefetching, emerging new edge services, and delivery of streaming content.

Book Description
If clients can share these cached files, the server's load can be reduced by a potentially large margin, making larger-scale systems possible. We introduce the notion of dynamic hierarchical caching, in which adaptive client hierarchies are constructed on a file-by-file basis. Trace-driven simulation and workload-driven runs of a prototype file system suggest that dynamic hierarchies can reduce server load substantially without the client performance penalties associated with more static schemes."

Book Description
The last decade has seen a tremendous growth in the usage of the World Wide Web. The Web has grown so fast that it seems to be becoming an unusable and slow behemoth. Web caching is one way to tame and make this behemoth a friendly and useful giant. The key idea in Web caching is to cache frequently accessed content so that it may be used profitably later. This book focuses entirely on Web caching techniques. Much of the material in this book is very relevant for those interested in understanding the wide gamut of Web caching research. It will be helpful for those interested in making use of the power of the Web in a more profitable way. Audience and purpose of this book This book presents key concepts in Web caching and is meant to be suited for a wide variety of readers including advanced undergraduate and graduate students‚ programmers‚ network administrators‚ researchers‚ teachers‚ techn- ogists and Internet Service Providers (ISPs).
