This book, at its core, is all about building your own set of tools from which you can draw inspiration as you work with SQL Server. I try to explain not only the hows of each concept described herein, but also the whys. And in many examples throughout the book, I attempt to delve into the process I took for finding what I feel is the optimal solution. My goal is to share with you how I think through problems. Whether or not you find my approach to be directly usable, my hope is that you can harness it as a means by which to tune your own development methodology.

This book is arranged into three logical sections. The first four chapters deal with software development methodologies as they apply to SQL Server. The next three chapters get into advanced features specific to SQL Server. And the final four chapters are more architecturally focused, delving into specific design and implementation issues around some of the more difficult topics I’ve encountered in past projects.

The primary purpose of this book is to bring Microsoft SQL Server developers back into the software development fold. These pages stress rigorous testing, well-thought-out architectures, and careful attention to interdependencies. Proper consideration of these areas is the hallmark of an expert software developer—and database professionals, as the core members of any software development team, simply cannot afford to lack this expertise.

In Securing VoIP Networks, two leading experts systematically review the security risks and vulnerabilities associated with VoIP networks and offer proven, detailed recommendations for securing them. Drawing on case studies from their own fieldwork, the authors address VoIP security from the perspective of real-world network implementers, managers, and security specialists. The authors identify key threats to VoIP networks, including eavesdropping, unauthorized access, denial of service, masquerading, and fraud; and review vulnerabilities in protocol design, network architecture, software, and system configuration that place networks at risk. They discuss the advantages and tradeoffs associated with protection mechanisms built into SIP, SRTP, and other VoIP protocols; and review key management solutions such as MIKEY and ZRTP. Next, they present a complete security framework for enterprise VoIP networks, and provide detailed architectural guidance for both service providers and enterprise users.

After numerous years as a market maker in the trenches of the New York Mercantile Exchange, few analysts know how to make money trading options like author Lee Lowell. In this well-rounded resource, Lowell shows both stock and commodity option traders exactly what works and what doesn't.

Filled with in-depth insight and expert advice, Get Rich with Options provides you with the knowledge and strategies needed to achieve optimal results within the options market. The book quickly covers the basicshow options are priced, strike price selection, the use of Delta, and using volatility to one's advantagebefore moving on to the four options trading strategies that have helped Lowell profit in this arena time and again: buying deep-in-the-money call options, selling naked puts, selling option credit spreads, and selling covered calls. Using these strategoes decisively, he says, is the fastest route to riches in the options trading game.
