Bill Karwin has helped thousands of people write better SQL and build stronger relational databases. Now he's sharing his collection of antipatterns--the most common errors he's identified in those thousands of requests for help. Most developers aren't SQL experts, and most of the SQL that gets used is inefficient, hard to maintain, and sometimes just plain wrong. This book shows you all the common mistakes, and then leads you through the best fixes. What's more, it shows you what's behind these fixes, so you'll learn a lot about relational databases along the way.

As C# developers get more experienced, there are a lot of things they pick up along the way that are really useful and important to know, even if they aren't necessarily directly code-related. One of those topics is XML comments, and I've been surprised at how many developers -- even really experienced ones -- don't use them, or even know about them. They're really useful, and they can help you build better software, even if they don't actually change the way your programs behave.

Part of the appeal of mobile applications is that you can take your application and its data with you wherever you go. One reality of mobile is, at times, a mobile device does not have a working connection to the Internet. This might seem to be an insurmountable problem for mobile Web applications. However, Web applications have evolved and become capable of working offline. In this article, you will learn how to offline-enable your mobile Web application and learn to detect when your application goes from offline to online and vice versa.

Systems optimization is a growing field, especially in adaptive, autonomic systems, but also in traditional information workflows. Much of the material accumulated in the monitor phase is available in some form of XML. Rather than apply complicated, monolithic analysis tools, you can benefit when you apply the pattern dispatch mechanisms inherent in XML. This saves effort and increases flexibility as it supports a library of analysis primitives that you can redeploy for high-level reports as well as fine-tuning. Learn to apply the likes of XPath and XSLT patterns much more broadly in order to support analysis and drive systems optimizations.

In this article, we present an approach for XML Validation using OASIS Content
Assembly Mechanism (CAM) templates to support a wide array of complex message
exchanges with business partners using B2B or B2C business patterns. The CAM
templates simplify and externalize the validation rules while allowing the gateway
to act as a pass-through on information that is not directly relevant. We also cover
our experiences using an open source component built using Eclipse and Java
technology to deliver the needed validation services. Follow the application development
process as it happened along with sample code snippets and an XML example using the
STAR (Standards for Technology in Automotive Retail) Automotive Business Object
Document (BOD) schema and associated CAM XML template.
