With both Microsoft .NET and Java development environments in mind, consultant and practitioner Nilsson takes a very logical approach to designing enterprise applications and document them in the form of patterns while embracing agile methods. He covers background issues as values to value, patterns, test-driven development and refactoring, then moves on to domain-driven design in a new default architecture, infrastructure and way of approaching rules, and then to patterns of enterprise application architecture within persistence and NHibernate. He works through several solid design techniques to embrace within context, SOA, inversion of control and dependency injection, and aspect-oriented programming, closing with information on the user interface, including mapping and wrapping. He also provides other domain model styles in an appendix for reference and a catalog of patterns described in the text. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)
