Creating a
DB Requester
Application
DB requester applications are data management applications that must be developed
quickly but are not used for business-critical tasks where maintaining database
integrity is essential. These applications can be used to add, maintain, or retrieve
information from one or more related tables or files in a database. DB requester
applications cannot perform calculations or data manipulations or, more importantly,
perform complex integrity checks on the database.
A DB requester application is composed of:
One or more DB (database) requesters that you create using the Pathmaker
product
The standard servers provided by the Pathmaker product
One or more MENU requesters (optional)
Standard services perform common database functions such as inserts, deletes, and
updates. These services are packaged into two standard servers provided by the
Pathmaker product, one for use with NonStop SQL databases and one for Enscribe
files.
The major tasks for creating a DB requester application are illustrated in Figure 3-6.

Note: Simulation of the application screens is an optional step that
can occur anytime after requesters have been added.
