Teil V
SQL in der Praxis
In diesem Teil…
Wenn Sie dieses Buch von Anfang an gelesen und fasziniert beobachtet haben, wie sich SQL vor Ihnen entfaltet, dann haben Sie SQL bis jetzt isoliert betrachtet – vielleicht haben Sie sogar davon geträumt, alle Datenverarbeitungsprobleme allein mit SQL zu lösen. Leider gibt es noch die Wirklichkeit. Viele Dinge können Sie mit SQL einfach nicht lösen, wenigstens nicht mit SQL allein. Wenn Sie SQL jedoch mit traditionellen prozeduralen Sprachen, zum Beispiel COBOL, Java, FORTRAN, Visual Basic oder C++, kombinieren, können Sie Ergebnisse erzielen, die Sie mit SQL allein nicht erreichen.
In diesem Teil zeige ich Ihnen, wie SQL mit prozeduralen Sprachen verbunden wird. Dann beschreibe ich, wie Sie mit externen SQL-Datenbanken arbeiten, die sich beispielsweise im Internet oder im Intranet Ihres Unternehmens befinden. Plötzlich sieht die Wirklichkeit ziemlich vielversprechend aus.
