In his long-awaited book, Martin Fowler has done for application domain patterns what the Gang of Four [Gamma et al.] have done for general purpose design patterns in their book, Design Patterns: Elements of Reusable Object-Oriented Software. This book is a must have for all analysts and designers doing object-oriented business modeling and business process re-engineering. —Donald G. Firesmith, Knowledge Systems Corporation Fowler shares with you his wealth of object modeling experience and his keen eye for identifying repeating problems and transforming them into reusable models. Analysis Patterns provides a catalogue of patterns that have emerged in a wide range of domains, including trading, measurement, accounting, and organizational relationships.
Michael Sipser's emphasis on unifying computer science theory - rather than offering a collection of low-level details - sets the book apart, as do his intuitive explanations. Throughout the book, Sipser builds students' knowledge of conceptual tools used in computer science, the aesthetic sense they need to create elegant systems, and the ability to think through problems on their own.

A very practical guide to making databases run faster and better. A poorly performing database application can cost each user time, and have an impact on other applications running on the same computer or the same network. This book will help DBAUs and programmers improve the performance of their databases.
If you’re writing one of several applications that call for asynchronous programming, this concise hands-on guide shows you how the async feature in C# 5.0 can make the process much simpler. Along with a clear introduction to asynchronous programming, you get an in-depth look at how the async feature works and why you might want to use it in your application. Written for experienced C# programmers—yet approachable for beginners—this book is packed with code examples that you can extend for your own projects. Write your own asynchronous code, and learn how async saves you from this messy chore Discover new performance possibilities in ASP.NET web server code Explore how async and WinRT work together in Windows 8 applications Learn the importance of the await keyword in async methods Understand which .NET thread is running your code—and at what points in the program Use the Task-based Asynchronous Pattern (TAP) to write asynchronous APIs in .NET Take advantage of parallel computing in modern machines Measure async code performance by comparing it with alternatives
Four centuries after humanity has colonized the galaxy, information freight companies are used as an alternative to electronic communication. On one of her frequent trips into deep space, Katmer Al-Shei, owner of one of the smaller information companies, is accused of smuggling artificial intelligence. When Al-Shei tries to clear her name, she uncovers conspiracy after conspiracy, all set against the backdrop of a looming war.
