* With typical Wrox thoroughness, this book covers every aspect of virtualization on the Linux platform for administrators seeking to optimize the use of enterprise hardware, create virtual environments geared toward specific tasks, or establish a testing environment
    * Provides a complete foundation in virtualization, XEN, and competing approaches with in-depth discussions of installing, configuring, and using XEN, including detailed examples of XEN configuration files, system configuration files, and system-level configuration information
    * Offers details that help system administrator adopt XEN and justify its selection
    * Covers optimizing XEN, XEN hosts, and guest operating systems for maximum performance and reliability; using XEN in enterprise data centers; procedures and considerations for building custom guest operating systems to run as virtual machines on a XEN host; and much more.

Since the initial work on constrained clustering, there have been numerous advances in methods, applications, and our understanding of the theoretical properties of constraints and constrained clustering algorithms. Bringing these developments together, Constrained Clustering: Advances in Algorithms, Theory, and Applications presents an extensive collection of the latest innovations in clustering data analysis methods that use background knowledge encoded as constraints.

Algorithms

The first five chapters of this volume investigate advances in the use of instance-level, pairwise constraints for partitional and hierarchical clustering. The book then explores other types of constraints for clustering, including cluster size balancing, minimum cluster size,and cluster-level relational constraints.

Theory :

It also describes variations of the traditional clustering under constraints problem as well as approximation algorithms with helpful performance guarantees.

Applications :

The book ends by applying clustering with constraints to relational data, privacy-preserving data publishing, and video surveillance data. It discusses an interactive visual clustering approach, a distance metric learning approach, existential constraints, and automatically generated constraints.

With contributions from industrial researchers and leading academic experts who pioneered the field, this volume delivers thorough coverage of the capabilities and limitations of constrained clustering methods as well as introduces new types of constraints and clustering algorithms.

Understand how to use the new features of Microsoft SQL Server 2008 for data mining by using the tools in Data Mining with Microsoft SQL Server 2008, which will show you how to use the SQL Server Data Mining Toolset with Office 2007 to mine and analyze data. Explore each of the major data mining algorithms, including naive bayes, decision trees, time series, clustering, association rules, and neural networks. Learn more about topics like mining OLAP databases, data mining with SQL Server Integration Services 2008, and using Microsoft data mining to solve business analysis problems.

It is nearly impossible today to write enterprise software without the use of one or more relational databases. Granted, there are cases when the data is transient and not stored in a database, but for the most part, software needs to consume and manipulate data in a database. It sounds easy, but there are hundreds of ways to connect software systems to databases and thousands of people who think they have the skeleton key for data access layers. Pro LINQ Object Relational Mapping in C# 2008 explains an efficient, repeatable way to apply industry design patterns to build scalable object–oriented data access layers.

Object relational mapping (OR/M) has been a gray area in Microsoft development for many years. It’s not that Microsoft language developers don’t understand OR/M; in fact, the opposite is true, as is exemplified by the glut of third–party .NET OR/M tools on the market. The struggle has come more from the lack of native tools with the object–oriented and object persistence capacity to effectively work in this arena. With the inception of .NET, Microsoft overcame the first obstacle by developing an object–oriented environment and framework. The second obstacle, the native object persistence layer, is only now being realized with the introduction of Language Integrated Query (LINQ) and LINQ’s children, the Language Integrated Query for Relational Databases (LINQ to SQL) and the Language Integrated Query for the ADO.NET Entity Framework (LINQ to Entities). The gray area no longer exists, and the .NET developers of the world finally have the native tools required to build modular, reusable data access layers.
What you’ll learn

    * The powerful advantages that OR/M can bring to your code
    * The native tools that are now available within Visual Studio 2008 for OR/M
    * How to build scalable object–oriented data access layers that take advantage of OR/M’s flexibility
    * How LINQ fits into this picture, together with the advantages and disadvantages that it can bring
    * How the concepts work in the real world by examining a fully worked and detailed case study, created with an architecture than can be easily applied to a wide range of other situations
