The Bubtangle
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 diagrams current.
- The industrial tooling necessary to create millions of Bubtangle
templates is available due to the depression.
- It will eliminate the bubbles vs. rectangles struggle, and permit
analysis teams to focus on other issues.
- Bubtangles are permissible for Nolan Stage 4/5 companies.
-The Bubtangle is 75% of a rectangle and 50% of a bubble,
yielding a 125% Bubtangle.
- It is nonprocedural, user friendly, and relational.
- It provides a meeting ground for proud bubble people and rectan-
gle people.
- It is Ada-compatible.
Undoubtedly, there are dozens of other advantages to stan-
dardized use of the Bubtangle, and I’d welcome any further in-sights.
