Overview

Acquire the skills you need to develop Pathway applications quickly and efficiently. Through classroom discussion and hands-on programming exercises with an HP NonStop™ server, you will advance your application programming skills in the Pathway environment. You will have the choice of performing lab exercises using either the Enscribe or the NonStop SQL/MP database. After completing this 5-day course, you will understand how Pathway applications utilize the features of the system architecture and operating system, and you will be able to apply what you have learned to your own application programs.
