THE BUBTANGLE As a data processing practitioner, I have had it with incompatibili- ties. Compilers are incompatible, operating systems are incompati- ble, database managers are incompatible, and even the ‘*process”’ symbol (Yourdon/DeMarco Bubble vs. Gane/Sarson Rectangle) for structured analysis is incompatible. I can't do anything about the operating systems or compilcrs but I do have a suggestion about the ‘process’ symbol. I hereby propose the Bubtangle, a standard- ization of the structured analysis 'process' symbol. The Bubtangle offers the data processing community the following advantages: - It integrates the best features of both the bubble and the rectangle. - Iis an internationally recognized symbol. - It sounds better then recle. -It is upwardly compatible (unlike COBOL-80) and does not obso- lete the current investment in bubble/rectangle technology. - It would permit the use of bubbles or rectangles at lower levels of decomposition, thus keeping all existing ...
