Apollo software

Calculations were performed on an IBM compatible 80486 computer and a HP Apollo 9000 series 700 model 715/75 using the SAS software package [23]. For prediction of values the SAS procedure PROC REG was used, subsequent calculations based on these R values were performed with a variety of home-written macros in the SAS system.

The creation of the concept of reuse definition scenarios during Apollo to save time in development and space in the software was a predecessor to the type of higher level language statements used within the systems language. This included horizontal and vertical reuse that led to a flexible open architecture within the DBTF environment. 

Understanding the importance of metrics and the influence it could have on future software has had a major focus throughout this endeavor. What this approach represents, in essence, is the current state of a reusable originally based on and learned from Apollo followed by that learned from each of its evolving states. It reuses and builds on that which was (and is) observed to have been beneficial to inherit as well as the avoidance of that observed not to have been beneficial. That learned from history was and will continue to be put into practice for future projects. Someone once said it is never surprising when something developed empirically turns out to have intimate connections with theory. Such is the case with DBTF. ...
