The Virtual Bookcase Reviews of 'Pattern Languages of Program Design':
Reviewer amazon.com wrote:Pattern Languages of Program Design is the first of three volumes of groundbreaking research on patterns, ranging from smaller-scale design patterns to larger patterns useful for software architecture and process engineering. Early chapters look at frameworks and components for engineering solutions to particular types of problems at a higher level, such as looking at patterns as "tools and materials" that can be used to solve problems effectively. The guide also discusses how to use patterns with interpreters and client-server systems. Distributed processing is a difficult and exciting area of computing, and patterns presented in Pattern Languages of Program Design can help solve some of the problems of scalability, concurrency, and transaction management. These patterns include several business objects for managing transactions and accounts, as well as for optimizing queries across distributed systems. The middle section of this text applies patterns to the software engineering process itself and several papers (including one intriguingly called "Caterpillar's Fate") show how the pattern movement can benefit software engineers and managers. Further material looks at the process of defining and implementing patterns. (Discovering patterns is only a start; learning to reuse them effectively is another challenge.) Final chapters look at patterns that manage state and events for real-time and behavioral systems. Although the first installment of Pattern Language of Program Design offers a decidedly mixed bag of essays, it is particularly strong on distributed systems and provides a strong overview of some central thinking on pattern research, which is still relevant.
Reviewer Rob Slade wrote:
The concept of a pattern, or framework, in object-oriented programming, is an
attempt to formalize program design or architecture. This is analogous to the
provision that high-level programming languages made for algorithms, as opposed
to mere libraries of machine-coded functions.
The material in the book is based on the presentations of the First Annual
Conference of Pattern Languages of Programs held in August 1994. As the
conference experimented with a "writers' workshop" format, so the book has
experimented with minimal imposition of structure on the original papers.
The result is a diverse collection, addressing a variety of audiences. Those
with expertise in object-oriented programming will find a number of papers
giving specific directions for particular tasks. Those with a solid feel for
object orientation and design may be interested in attempts to extract object
patterns from nonobject-coded programs. Those interested in the theory of
programming will find a number of philosophical issues raised.
One reader the book is *not* for, though, is the novice. The conference was a
meeting of professionals, and the book spares no time for explanation or
tutorial. The experienced, but not object-oriented, programmer may find some
of the material to be rather vague, although startlingly similar to general
ponderings of the programming process, as it always has been.
