For all the buzz about trendy IT techniques, data processing is still at the core of our systems, especially now that enterprises all over the world are confronted with exploding volumes of data. Database performance has become a major headache, and most IT departments believe that developers should provide simple SQL code to solve immediate problems and let DBAs tune any "bad SQL" later. In The Art of SQL, author and SQL expert Stephane Faroult argues that this "safe approach" only leads to disaster. His insightful book, named after Art of War by Sun Tzu, contends that writing quick inefficient code is sweeping the dirt under the rug. SQL code may run for 5 to 10 years, surviving several major releases of the database management system and on several generations of hardware. The code must be fast and sound from the start, and that requires a firm understanding of SQL and relational theory. The Art of SQL offers best practices that teach experienced SQL users to focus on strategy rather than specifics. Faroult's approach takes a page from Sun Tzu's classic treatise by viewing database design as a military campaign. You need knowledge, skills, and talent. Talent can't be taught, but every strategist from Sun Tzu to modern-day generals believed that it can be nurtured through the experience of others. They passed on their experience acquired in the field through basic principles that served as guiding stars amid the sound and fury of battle. This is what Faroult does with SQL. Like a successful battle plan, good architectural choices are based on contingencies. What if the volume of this or that table increases unexpectedly? What if, following a merger, the number of users doubles? What if you want to keep several years of data online? Faroult's way of looking at SQL performance may be unconventional and unique, but he's deadly serious about writing good SQL and using SQL well. The Art of SQL is not a cookbook, listing problems and giving recipes. The aim is to get you-and your manager-to raise good questions.

Storing large object data in the database offers a number of benefits, but introduces performance challenges. Conversely, storing large object data in the file system has overriding performance advantages, but fails to offer some of the basic data integrity, security and manageability features that are required for business data, and which SQL Server provides. Up to now, most people have adopted file system storage by necessity, and often struggled to overcome the associated shortcomings. This is exactly where SQL Server's new FILESTREAM feature fits in. Introduced in SQL Server 2008, it is implemented as an extension to the VARBINARY(MAX) data type and allows large object data to be stored in a special folder on the NTFS file system, while bringing that data under the transactional control of SQL Server. This book guides you step-by-step through every phase of FILESTREAM implementation, from enabling the feature, to creating FILESTREAM tables, to manipulating FILESTREAM data through the streaming APIs. We also cover, in detail, administration and troubleshooting of FILESTREAM databases and tables.No feature is used in isolation, so we devote several chapters to explaining how this new feature can be integrated into ASP.NET and Silverlight web applications, and into applications using Entity Framework. We also take a look at how well FILESTREAM plays with other SQL Server features such as SSIS and SSRS, pointing out various issues and pain-points along the way. We also devote a full chapter to the FileTable feature, a long-awaited new addition to FILESTREAM, with SQL Server 2012, which allows Windows applications to access FILESTREAM data exactly as is it were stored directly on the file system. We hope this book will get you started, quickly, with FILESTREAM, and then help you master all essential aspects of programming and administering FILESTREAM-enabled databases.

Execution plans show you what's going on behind the scenes in SQL Server. They can provide you with a wealth of information on how your queries are being executed by SQL Server, including: Which indexes are being used, and where no indexes are being used at all. How the data is being retrieved, and joined, from the tables defi ned in your query. How aggregations in GROUP BY queries are put together. The anticipated load and the estimated cost that all these operations place upon the system. Grant Fritchey's book is the only in-depth look at how to improve your SQL query performance through careful design of execution plans. Sample chapters of the ebook have garnered stunning reviews, such as: "All I can say is WOW. This has to be the best reference I have ever seen on Execution Plans in SQL Server. My hats off to Grant Fritchey" Jonathan Kehayias.

Hacker is a person who uses his creativity and knowledge to overcome limitations, often in technological contexts. Introduction About Hacking If you ask a random person on the street what a hacker is, they might recall ever seeing the word in connection to some criminal who `hacked' some website and stole for example credit card-data. This is the common image the media sketches of the `hacker'. The somewhat more informed person might think that a hacker is not really a criminal but somebody with a lot of knowledge about computers and security. Of course this second definition is a lot better than the first one, but I still don t think it catches the essence of what makes one a hacker. First of all, hacking hasn't necessarily got to do with computers. There have been hackers in the Medieval Ages and maybe even in the Stone Ages. The fact that they used other means to express their skills and knowledge doesn't make them less than any hacker in the modern ages. We are just blessed with the fact that at this moment we are all surrounded by technology, a lot of people even are dependent of it.
