Custom Applications are defined as computer programs created to
perform a specific computational task in a manner not available in the
standard function sets of commercially available software products.
Developed in any type and level of computer language for any type of
hardware and software environment, these specialized programs have a
uniqueness derived from the individual requirements and details of the
Examples of Custom Applications include:
- Commercial software that has, through the purchase and alteration
of the product's source code, been made unique.
- Software developed by an independant software consultant/engineer
for a specific purpose.
- Software written to be used interpretively with
commercial software products e.g., database or spreadsheet
- User defined formulas and calculations that manipulate user data files.
The complexity of just one of these programs is described in our Database Example.
Safe Approach to Custom Applications
To adequately address Y2K issues with Custom Application, a
thorough understanding of the programmatic logic and
inter-relationships with other systems is required. It is highly
recommended that you contact the original author/developer of any
application that falls under this category. Fixing custom applications
is difficult and should not be undertaken by the novice. Solutions to
Y2K problems found in custom applications may involve several
complex steps that only a skilled programmer should undertake.
