Abstract

The purpose of this report is to provide technical input to the Deputy Assistant Secretary of the Air Force for Communications, Computers, and Logistics to assist that office in preparing a business case for using ADA or C++ to develop Corporate Information Management (CIM) systems. This technical input has been gathered by using the comparison methodology of a 1985 Federal Aviation Administration (FAA) report as a model, as well as by conducting interviews with experts in ADA and C++. The conclusion of this report is that technically neither language is clearly better than the other; for government use, however, there is clear justification and rationale for using ADA rather than C++ for large complex systems with long lifetimes.
