Microsoft_SQL_Server_2008_A_Beginner's_Guide 英文版

Microsoft SQL Server 2008: A Beginner’s Guide follows three previous editions that covered SQL Server 7, 2000, and 2005. Generally, all SQL Server users who want to get a good understanding of this database system and to work successfully with it will find this book very helpful. (If you are a new SQL Server user but understand SQL, read the section “Differences Between SQL and Transact-SQL Syntax” later in this introduction.) This book addresses users of all components of the SQL Server system. For this reason, it is divided into several parts: users who want to learn more about the relational database component called Database Engine will find the first three parts of the book the most useful. The fourth part of the book is dedicated to business intelligence users who use either Analysis Services or relational extensions concerning BI. The last part of the book provides insight for users who want to use XML data and/or spatial data.

LINQ Unleached For C Sharp(1/2)

共2个压缩包,这是第1个 Foreword Data affects just about every aspect of our lives. Everything we do is analyzed, scrutinized, and delivered back to us in the form of coupons and other marketing materials. When you write an application, you can be sure that data in one form or another will be part of the solution. As software developers, the ease with which we can store, retrieve, and analyze data is crucial to our ability to develop compelling applications. Add to that the fact that data can come in a number of different shapes and formats, and it quickly comes to light that there is tremendous value in a consistent framework for accessing many types of data. Several different data access approaches have been developed for Windows developers over the years. ADO and OLEDB and subsequently ADO.NET gave us universal access to relational databases. MSXML and ADO.NET made it possible to inspect and manipulate XML documents. Each of these technologies had their benefits and drawbacks, but one common thread ran through each of them: They failed to deliver data access capabilities in a way that felt natural to developers. LINQ now makes data access a first-class programming concept in .NET, making it possible for developers to express queries in a way that makes sense to developers. What makes LINQ unique is that it enables programmers to create type-safe data access code complete with Intellisense support and compile time syntax checking. Paul Kimmel has done an excellent job of presenting LINQ in a concise and complete manner. Not only has he made LINQ approachable, but he has also masterfully explained concepts such as Anonymous Types and Lambda Expressions that help make LINQ a reality. The sample code throughout the book demonstrates the application of the technology in a clear and meaningful way. This is a great “Saturday morning with a pot of coffee” kind of book. I hope you’ll dive in and get as much out of this book as I did. Darryl Hogan Architect Evangelist, Microsoft

Illustrated C# 2005.pdf(1/3)

请注意: 共3个RAR包,这是第1个 Publisher's description Illustrated C# 2005 doesn’t use the traditional dense prose format of most programming texts. Rather, it presents the C# programming language in a unique visual manner. The book uses three techniques to achieve this: concise text; tables that clarify and summarize language features; and frequent figures and diagrams. Each feature is also illustrated with concise, focused code samples. The book starts with an overview of the .NET platform and the role played by C#, then quickly delves into the language. It covers the entire C# language, including new features added in C# 2.0 as well as the most complex topics. It’s an ideal read if you’re a migrating C++ or VB programmer who already knows how languages work. Despite its title—which might give the impression that it’s a lightweight treatment of the language—this book is anything but. With its clean visual format, you’ll be able to learn the material more quickly and retain it better than you would with a typical C# 2005 book. Even experienced programmers may come away from it with a deeper understanding of the language
