Application Program Interfaces (APIs) are powerful, built-in tools
used to solve business problems. Many System i programmers,
however, do not have a working knowledge of the APIs available
within i5/OS. Worse still, programmers who are familiar with the
use of APIs may not be taking full advantage of the APIs and
processing techniques available to them.
In this book, author and noted IBM API expert Bruce Vining is your
guide to making sense, and effectively mastering, the wide variety
of APIs available with System i. Each chapter is full of real
business-world examples that you can modify and use in your own
environment.
In recent years, the business programmer has had to integrate
applications-often from different operating systems and programming
platforms-using different languages to integrate business rules and
requirements. APIs allow you to gain access to the underlying
structure of an application. With this book you will soon realize
that APIs are among the most powerful tools in your toolbox.
