- Abstract
- Regelmäßig werden Fragen gestellt wie "Was für ein Standard-Datenbanksystem steckt in allegro?" oder "Kann man eine allegro-Datenbank mit SQL abfragen?" Es zeigt sich in solchen Unterhaltungen immer wieder, dass der eine sehr viel von relationalen Datenbanken versteht, von allegro aber ganz wenig, bzw. umgekehrt. Dann wird es mühsam und Fehleinschätzungen sind auf beiden Seiten vorprogrammiert. Um diesem Missstand abzuhelfen und das gegenseitige Verstehen zu fördern, wird hier der Versuch gemacht, vergleichende Aussagen zu den Konzepten und Eigenschaften der beiden Datenbankwelten zu machen, und zwar mit möglichst wenig Fachjargon und mit Blick mehr auf die Praxis als auf die Theorie. Diese "Welten" sind von höchst unterschiedlicher Größe und Bedeutung, das ist klar, doch darum geht es hier nicht, schon gar nicht um die immer nur für konkrete Anwendungen, aber nicht allgemein entscheidbare Frage "Was ist besser?". Wer aber wegen eines konkreten Projekts vor eben dieser Frage steht, soll hier Hilfen zur Einschätzung erhalten. Fakt ist auch, dass immer wieder relationale Daten nach allegro überführt werden bzw. Datenaustausch in umgekehrter Richtung stattfinden soll, und auch dabei können ein paar übergreifende Kenntnisse nützen. Gewiss kann man noch viel mehr sagen, vermutlich müssen einige der Aussagen weiter präzisiert oder modifiziert werden. Jeder Leser ist eingeladen, konstruktive Kritik zu üben, damit wir diese Übersicht verbessern und in der nächsten "news"-Ausgabe veröffentlichen können.
