Application Design Fundamentals

Methodologies for good computer application design were first devised in the 1960s by recognized industry consultants such as James Martin, Edward Yourdon, and Larry Constantine.

Today’s application development technologies make building an application much cheaper and quicker. In fact, the pace of computing is several orders of magnitude faster than it was just a decade ago.
