Chapter
Distributed Concurrency Control
As we discussed in Chapter 10, concurrency control deals with the isolation and consistency properties of transactions. The distributed concurrency control mechanism of a distributed DBMS ensures that the cons...

Chapter
Data Replication
As we discussed in previous chapters, distributed databases are typically replicated. The purposes of replication are multiple: 1. System availability. As discussed in Chapter 1, distributed DBMSs may remove sing...

Chapter
Distributed Object Database Management
In this chapter, we relax another one of the fundamental assumptions we made in Chapter 1—namely that the system implements the relational data model. Relational databases have proven to be very successful in ...

Chapter
Introduction
Distributed database system (DDBS) technology is the union of what appear to be two diametrically opposed approaches to data processing: database system and computer network technologies. Database systems have ta...

Chapter
Distributed Database Design
The design of a distributed computer system involves making decisions on the placement of data and programs across the sites of a computer network, as well as possibly designing the network itself. In the case of...

Chapter
Data and Access Control
An important requirement of a centralized or a distributed DBMS is the ability to support semantic data control, i.e., data and access control using high-level semantics. Semantic data control typically includ...

Chapter
Query Decomposition and Data Localization
In Chapter 6 we discussed a generic layering scheme for distributed query processing in which the first two layers are responsible for query decomposition and data localization. These two functions are applied...

Chapter
Multidatabase Query Processing
In the previous three chapters, we have considered query processing in tighly-coupled homogeneous distributed database systems. As we discussed in Chapter 1, these systems are logically integrated and provide ...

Chapter
Introduction to Transaction Management
Up to this point the basic access primitive that we have considered has been a query. Our focus has been on retrieve-only (or read-only) queries that read data from a distributed database. We have not yet cons...

Chapter
Distributed DBMS Reliability
We have referred to “reliability” and “availability” of the database a number of times so far without defining these terms precisely. Specifically, we mentioned these terms in conjunction with data replication...

Chapter
Parallel Database Systems
Many data-intensive applications require support for very large databases (e.g., hundreds of terabytes or petabytes). Examples of such applications are e-commerce, data warehousing, and data mining. Very large...

Popularity-aware prefetch in P2P range caching
Unstructured peer-to-peer infrastructure has been widely employed to support large-scale distributed applications. Many of these applications, such as location-based services and multimedia content distributio...

A framework for testing DBMS features
Testing a specific feature of a DBMS requires controlling the inputs and outputs of the operators in the query execution plan. However, that is practically difficult to achieve because the inputs/outputs of a ...

Distributed XML Query Processing
Over the past decade, XML has become a commonly used format for storing and exchanging data in a wide variety of systems. Due to this widespread use, the problem of effectively and efficiently managing XML col...

Dynamic Skyline Queries in Large Graphs
Given a set of query points, a dynamic skyline query reports all data points that are not dominated by other data points according to the distances between data points and query points. In this paper, we study d ...

Chapter
Efficient Decision Tree Re-alignment for Clustering Time-Changing Data Streams
Mining streaming data has been an active research area to address requirements of applications, such as financial marketing, telecommunication, network monitoring, and so on. A popular technique for mining the...

XCube: Processing XPath queries in a hypercube overlay network
In this paper, we present the design and performance of XCube, a tag-based system for managing XML data in a hypercube overlay network. In XCube, each node in a d-dimensional hypercube is identified by a d-bit ve...

Distributed XML Processing
XML is commonly used to store data and to exchange it between a variety of systems. While centralized querying of XML data is increasingly well understood, the same is not true in a scenario where the data is ...
