Abstract
Will man sich auf dem weiten Feld der Datenverarbeitung die Entwicklungsstadien der letzten drei Jahrzehnte vergegenwärtigen, ist es hilfreich, mindestens vier Aspekte in den Blick zu nehmen: - Hardware: Industrie, Systeme - Software: Programmierung, Sprachen, Entwicklungssysteme - Software: Konkrete Anwendungsfelder, z.B. Bibliothekswesen - Bestimmte Anwendungssysteme, z.B. allegro-C Am Beispiel des an der UB Braunschweig entstandenen Systems allegro-C, dessen Entwicklung 1980 begann und bis heute andauert, lassen sich die Trends, die Evo- und Revolutionen der 30 Jahre nachverfolgen, und dies wird hier versucht. Die Stationen und Etappen der allegro-Geschichte sind knapp aufgelistet in einer Chronik, die ihrerseits im Kern eine spezialisierte allegro-Datenbank ist. Für die Anfangszeit bis Ende 1994 existiert eine ausführliche Darstellung der Entwicklung von Torsten Ahlers.
