This section presents an overview of the three major groups of tasks performed during
a Pathmaker application development effort. These tasks are based upon the
suggested life cycle for a Pathmaker application outlined in the Introduction to
Pathmaker manual. Some of the tasks listed here are optional, others are required.
Which optional tasks you choose to perform depends upon the complexity of the
application being implemented, the experience level of the application developers
working on the project, and the requirements of your organization. After reading this
section you should have a clear idea of the flow of a typical Pathmaker application
development effort. The details required to complete the tasks outlined in this section
are provided in the remainder of this manual and in the Pathmaker Reference Manual.
This section also briefly discusses using the Pathmaker product during the
development of client/transaction server applications for a Tandem system.
Preparing for
Pathmaker Application
Development
There are several major tasks that should be completed during preparation for a
Pathmaker application development effort. These tasks, summarized in this
subsection, are discussed in detail in Section 2 of this manual, “Preparing for
Pathmaker Application Development.”
Prerequisites Individuals preparing for a Pathmaker application development effort should be
familiar with the following Tandem products:
Data Definition Language (DDL)
Pathway
COBOL85 or C
NonStop SQL or Enscribe
Enform, FUP, PERUSE, TEDIT, SCUP
In addition the following skills and knowledge are needed:
Understanding of the architecture of applications produced using the Pathmaker
product and the concept of a Pathmaker project, as described in the Introduction to
Pathmaker manual.
Ability to design a Pathway application.
Tandem recommends that individuals who are new to the Pathmaker product should
use the product to develop a simple test application before designing a production
application or planning a production application development effort. Developing a
simple test application provides an opportunity for you to look at the source code that
the Pathmaker product generates, to understand what information an application
developer needs to most efficiently use the product, and to decide how Pathmaker
projects should be customized for your particular development environment.
