دانلود کتاب POJOs in Action: Developing Enterprise Applications with Lightweight Frameworks

Despite the fact that it was written a few years ago, it is no less valuable today in helping developers understand how to create an application architecture using the Domain Model approach. I have been using the Exposed Domain Model architectural pattern ever since I began using the Spring framework a few years ago, although I had no idea that's what it is called until reading this book. I really appreciated how the author compared its use with the façade-driven Domain Model architectural pattern.

It provides a brief introduction to the Spring Framework and Hibernate (as well as JDO), and covers at least enough material on each in order to demonstrate how to put both to use (together) in the example application that is used throughout the book. But it would be best to consult any of the numerous books and/or web resources that target those technologies specifically for more background and up-to-date implementation reference.

Other than a simple Servlet example in the Exposed Domain Model chapter, the book does not cover the Presentation layer - the focus is on the Business/Model layer.

Certainly the development framework landscape has changed and evolved since this book was published, but it's still a great practical resource which remains relevant in addressing important facets of application architecture that need to be considered and planned out.
