The four key reasons to
develop applications in a Fourth Generation Language such as PRO-IV are Productivity,
Maintenance, Quality and Industrial Strength.Productivity
PRO-IV significantly increases the productivity of the developers and
the quality of the applications they produce.
The use of:
a Structured development environment common Centralized Data Dictionary
reusable Objects (Look Up windows, Validation Tables etc.)
extensive suite of development utilities multiple Documentation points
and the insulation of the developer from the operating environment, enables the rapid
development of high quality, highly sophisticated applications.
Maintenance
Maintenance and modification of the application is extremely easy.
Changes made to any object, are immediately available anywhere in the application where
the object is called. Documentation of files, functions and data definitions are
automatically prepared and maintained for every application. PRO-IV automatically captures
system changes, thus ensuring that the system documentation is always current. A well
documented application is much easier to maintain.
Quality
The key PRO-IV concept is to enable the re-use of pre-written, error
free software components. These components are combined to form the business application,
thus ensuring a high degree of quality from the start.
Industrial Strength
A key strength of the product is its proven ability to build
"Industrial Strength" applications that can be deployed across a multitude of
hardware platforms, operating environments and RDBMS/Filing systems. |
