Summary and Info
This book focuses on integrating J2EE with mainframe applications. The patterns described in the book demonstrate how to encapsulate an integration tier that shields the J2EE elements of an application from the legacy elements, so Java applications can take advantage of existing mainframe code.
The book goes through a real-life example by describing a banking integration project. With this example it describes the common integration patterns, DTO, DAO, Local Transaction Cache, etc. One of the major points the authors make is the benefit from having a common domain model across the enterprise. The common domain model will provide a consistent business data model across an enterprise for all users, so everyone in the organization will have a common vocabulary.
If you are a Java developer who is involved with integrating mainframe application this book is an excellent resource to have on the subject. This book is a concise and practical guide to enterprise integration.
