Overview
Jeri Edwards takes you on a rare, international tour of eight large companies' client/server applications that are at work in enterprises today. You'll get an insider's peek at these companies' projects. Find out what went right, and what they would do differently next time. You'll learn why 3-tier architectures are key to successful enterprise client/server applications; how to migrate from monolithic, single-tier applications to multi-tier client/server; what today's middle-tier platforms are - including TP Monitors, ORBs, MOMs, and RPCs - and when to use them; what the architectural trade-offs are and how to choose between them; how successful projects are run and what outcomes to expect; and words to the wise: tips from the architects.Editorials

The Barnes & Noble ReviewPack your bags, grab your helmet: you're going on a guided tour of the world's largest, most impressive 3-tier client/server projects. Your tour leader will be Jeri Edwards, she of the legendary Orfali/Harkey/Edwards team of best-selling client/server consultants (they wrote the legendary Essential Client/Server Survival Guide). In Edwards' new 3-Tier Client/Server at Work, Revised Edition, you won't just take the senior citizens' bus tour: you'll get behind the scenes, discovering why key decisions were made, and getting specific advice from the architects.
Along the way, Edwards demonstrates how Wells Fargo used BEA's ObjectBroker to build a Customer Relationship System that integrates access to all of a customer's accounts — banking, brokerage, and insurance — and delivers the information wherever it's needed, to customer service reps, ATMs, voice response systems, and customer service reps alike. See how PeopleSoft approached migrating its core business applications from classic two-tier to n-tier in three orderly phases, eliminating the need for database replication and allowing customers to use the latest PeopleSoft technology even if they haven't simultaneously upgraded all their systems. There's a look inside the 3-tier system that delivered a 30% increase in throughput at Hong Kong International Terminals, the world's largest privately-owned container terminal.
Edwards also presents quick, readable tutorials on the 3-tier technologies that really matter, especially Object Transaction Monitors — and ten rules for 3-tier successworthtaking to heart. — Review by Bill Camarda (Contributing Editor)
