DESCRIPTION

Jaguar Development with PowerBuilder 7 is the definitive guide to distributed application development with PowerBuilder. It is the only book dedicated to preparing PowerBuilder developers for Jaguar applications and has been approved by Sybase engineers and product specialists who build the tools described in the book.

Jaguar Development with PowerBuilder 7 focuses on getting you up to speed on Jaguar and PowerBuilder, and it is packed with code samples to guide you every step of the way. It covers each step involved in application development, from setting up the development environment to deploying a production application.

Even a PowerBuilder developer with no experience in distributed technologies or Jaguar CTS will learn what it takes to build an application. Jaguar Development with PowerBuilder 7 covers:

• Developing Component-centric Applications
• Building Jaguar CTS Components/Clients
• CORBA
• Adaptive SQL Anywhere
• Adaptive Server Enterprise

and lots more!

WHAT THE EXPERTS SAY ABOUT THIS BOOK...

"Boy, was I pleasantly surprised! … all the topics are described from ground zero. The author does not assume an in-depth knowledge of any application server related subject matter…provides a detailed description on PowerBuilder component design as well as client applications. The tips, notes and warnings are very appropriate and should save valuable hours of development time… the book will meet and exceed anyone's expectations.

Jaguar Development with PowerBuilder 7 by Michael Barlotta provides a solid application server foundation for any PowerBuilder developer. It offers a platform from which anyone can confidently dive into the world of enterprise e-commerce and e-business application development."
--Boris Gasin, Dynamic Technology Group, Inc., for PFC Guide

"I hold in suspect the ambition and foresight of any PowerBuilder programmer that does not purchase this book. It is not a good book -- it is a must have."
--Rik's PowerBuilder Dojo

"Jaguar Development with PowerBuilder 7 has got to be one of the best books from Manning Publications I have ever reviewed. If you are new to DPB and looking for a good reference, this is the book. It is a fantastic book on the topic and will lead you through all the steps necessary to be successful with Jaguar. I wish this publication was available when I was first learning Jaguar. It definitely would have saved me some sleepless nights. This is a must have for any Jaguar developer - no matter what level."
--Jon Credit, Credit's Corner
