I've a query about the book, does is provide examples/problems where using patterns helped in improving the software solution? I know that lots of resources explain the patterns in a example-per-pattern approach where they start by the pattern, cons/bros, sample code ... etc without any real/hard example of how to utilize these patterns as a group to solve a domain problem.
thanks for the question. Examples show up in a few ways within the book. In chapter 1 (which is the sample chapter available for download) you can see reference to the use of PBE within real-life situations and some of the results of that application. Chapter 2 provides examples of a selection of pattern implementations - explaining the pattern and how it was automated.
The next major portion of the book is a detailed case study discussing a fictional team as they look to adopt PBE and enhance how they work with patterns in delivering a solution. A number of project iterations are discussed as we see the team leverage both pattern specifications and then create and use a pattern implementation. Throughout the case study reference is made to the PBE Patterns and Guidelines and PBE Practice elements that are used by the team. The case study ends up showing how the different pieces available fit together and can be used by the team -> providing a big picture view.
Part 3 in the book, is a reference section that details the PBE Patterns and Guidelines. Many examples for each of these elements is provided.
