About the Book

Bachelorarbeit aus dem Jahr 2003 im Fachbereich Informatik - Angewandte Informatik, Note: 1,3, Technische Universität München (Lehrstuhl 3), Sprache: Deutsch, Abstract: Bei der Entwicklung von Informationssystemen spielt die Anforderungsanalyse eine sehr wichtige Rolle. Fehler, die in dieser Phase begangen werden, sind im weiteren Verlauf der Entwicklung sehr kostspielig. Umso wichtiger ist es, die von den zukünftigen Anwendern genannten Anforderungen möglichst vollständig und korrekt zu erfassen und in einem konzeptionellen Modell darzustellen. Die Darstellung soll zum einen für den Anwender verständlich sein und zum anderen soll sie dem Entwickler als Grundlage des zu entwickelnden Informationssystems sein. Für die Darstellung der Anforderungen sind in den vergangen Jahren eine Reihe von Methoden und Verfahren entwickelt worden. In der Praxis haben sich im Bereich Datenbankentwurf zwei Datenmodelle durchgesetzt: (E)ER-Modell, basierend auf dem ER-Modell von Chen mit einigen Erweiterungen, und das UML-Klassenmodell. Im Bereich der Softwareentwicklung wurden immer mehr rechnergestützte Werkzeuge eingesetzt, die eine fehlerlose Entwicklung von Softwaresystemen unterstützen sollten. Diese Werkzeuge werden unter dem Begriff CASE-Tools (computer aided software engineering) zusammengefasst. In den 80er Jahren fanden diese Tools erstmals auch im Bereich Datenbankmodellierung ihren Einsatz. Entweder wurden neue Tools entwickelt oder Softwareentwicklungstools wurden für den Einsatz der Datenbankentwicklung angepasst. Vorliegende Arbeit soll einen Einblick in eine Auswahl vorhandener Tools bieten, und die Wahl eines passenden Werkzeuges unterstützen. Bei der Bewertung der Softwarewerkzeuge spielen allgemeine Aspekte wie z.B. Diagrammtypen und Funktionalität ebenso eine Rolle wie Anforderungen, welche speziell in diesem Praktikum an die Software gestellt werden. Getestet wurde eine Auswahl von drei Softwarewerkzeugen. Unter den getesteten CASE-Tools sind: - PowerDesigner von
