Query: Creating the App. Infrastructure is the core problem....

This book makes excellent points about the importance of thinking about application frameworks, not isolated apps. The thing that I learned from this book was that large companies need to make their investments in app. frameworks -- integrated set of interlocking applications -- very carefully. This is especially true for companies moving to e-business.The book does have its flaws. But, all in all as a first book on e-business application infrastructure it is an excellent one. It tells the story extremely well and is a handy reference.I hope that the authors are going to put out a second edition soon. A lot has changed in the last year since the book has been published. It would be good if the authors updated the book and added more chapters like Application Service Providers (ASP) and also a chapter on implementation issues/challenges. They can title the next edition "e-business 2.0" :-)
