|  | What is Rational Developer for System z?
Rational Developer for System z (RDz) is an Eclipse-based integrated
development environment that provides support for the development of a
multitude of different applications for z/OS.
It consists of a server part that is installed on z/OS and a client
part that is installed on your laptop and configured to communicate
with z/OS.
This tutorial shows how to create a COBOL stored procedure that
manipulates XML data in DB2 for z/OS. This is done through the Data
Perspective, which can be seen in Figure 1. A
perspective is a set of explorers and windows, each with a dedicated
purpose, collected in one screen and aimed at performing a certain
type of development task. Examples of perspectives are the Web
Perspective, the Java Perspective, and the z/OS Projects
Perspective.
Figure 1. The Data
Perspective in RDz
The Data Perspective consists of five explorers or windows:
- The Data Project Explorer (1) shows the different projects and the
artifacts you have created within these projects.
- The Data Source Explorer (2) shows the databases you have defined
and allows you to connect to them and work with objects in
them.
- The Remote Systems (3) shows the z/OS systems defined and allows
you to connect and work with them.
- The editor, in the middle of the page, (4) is used to edit
whichever type of artifact you are working on (for example, a
COBOL program or an SQL script).
- The bottom window (5) is a status/error/task bar showing
information about the current situation or last performed
task.
Whenever appropriate in the following sections, figures may show only
the relevant explorer or window, instead of the whole RDz screen.
