There is a VAX program called Structured System Analysis Design Methodology
(SSADM), a generic term as well as the product name for the VAX program. It
designs systems to run warehouses, handle orders and delivery notes, and so
on. The program checks that the designer doesn't use variables with the
same name in different areas and automates many other parts of the design
process.
Is there a similar program available for the Macintosh?
There are several programs for the Macintosh designed to help in Structured
Analysis and Design. For more information, search in the Redgate Buyer's
Guide Library using the search term "Case and Tools" or "Design and Tools".
