Patterns Of Enterprise Application Architecture Ebook

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms. This book started after Dave Rice and I gave some talks on J2EE architecture and mulled over how the concepts we had learned in C++, Forte, CORBA, and. Catalog of Patterns of Enterprise Application Architecture. Last Significant Update : January A short summary of the patterns in Patterns of Enterprise.

The project was one of those ambitious enterprise application projects: a back-end leasing system. Essentially what this system does is to deal with everything that happens to a lease after you've signed on the dotted line. It has to deal with sending out bills, handling someone upgrading one of the assets on the lease, chasing people who don't pay their bills on time, and figuring out what happens when someone returns the assets early. That doesn't sound too bad until you realize that leasing agreements are infinitely varied and horrendously complicated. The business "logic" rarely fits any logical pattern, because after all its written by business people to capture business, where odd small variations can make all the difference in winning a deal. Each of those little victories is yet more complexity to the system.

I picked these languages because most software developers can read them, not because of any particular coupling or opinions about the language. The main topic areas are: I've been fortunate enough to have some excellent contributors to this book, most notably Dave Rice - who wrote a good tenth of it. I wrote this book in the early noughties, but my colleagues and I find the patterns are still relevant today.

Our hypothesis then was that the essential problems and solutions in software architecture don't really change that much - that certainly has been true for the last decade. Another change since I wrote the book is that many patterns are now implemented by common frameworks particularly with database interaction.

This doesn't mean that developers no longer need to understand this material.

This is a collection of tricks, schticks, and small-A architectures that just tend to show up repeatedly in the wild. Martin Fowler, with his perspective as an idea man and his position as a consultant and thought leader, has obse I think this is a great book. Martin Fowler, with his perspective as an idea man and his position as a consultant and thought leader, has observed these and collected them together in a catalog along with some weighty analysis.

An initial read-through is probably a good idea, at least enough to assimilate the introduction and be familiar with the existence of most of the patterns. Out of real-world context, the material feels to me to be very academic and not very practical. Where it comes together is when I can use the book like a bird guide whilst bird watching: Digging through some code or design docs and stumbling on a mechanism, conceived and implemented by an author who may not have ever heard of PoEAA, and having some recognition like "Hey, this is very similar to a Query Object pattern.

Sometimes it helps the task at hand by filling in as the missing documentation; other times it's merely "fun facts". I've also used this book when putting together my own designs. It can provide useful guidance "What's an alternative if I don't like our offline locking". In both of the above uses, the book shines when I have a pattern already in front of me and I want to know more.

Probably as I get more practice out of putting context into Fowler's analysis, I'll be able to get direct practical value rather than food-for-thought out of working it the other way - starting with the academic discussion and being able to visualize real-world tailored specifics rather than idealized implementations.
