After the preparation for a Pathmaker application development effort has been
completed, it's time to construct and test the requesters, services, and servers for the
application.
This section explains how to use the Pathmaker full screen interface to accomplish the
application development tasks. It identifies the specific Pathmaker screens used for
each task and provides check lists to help you track your progress as you develop an
application.
You can also use the Pathmaker Application Definition Language (PMADL) to create
requesters, services, and servers for an application. Refer to the PMADL section of the
Pathmaker Reference Manual for details about using PMADL.
This section also provides information about how to maintain a Pathmaker
application, because many of the tasks performed during application maintenance are
the same as those performed during application development.
Prerequisites Individuals developing a Pathmaker application should be familiar with the following:
Basic Pathmaker and Pathway concepts including the architecture of applications
produced using the Pathmaker product and the concept of a Pathmaker project, as
described in the Introduction to Pathmaker manual.
COBOL85 or C
NonStop SQL or Enscribe
Enform, FUP, PERUSE, TEDIT, SCUP
In addition, knowledge of the following is helpful:
Data Definition Language (DDL)
Pathway
Note Anyone new to the Pathmaker product should use the product to develop a small test application before
developing a production application. Developing a test application provides an opportunity for you to
thoroughly understand the process of creating Pathmaker services, servers, and requesters and to look at
the source code that the Pathmaker product generates.
