Anforderungsanalyse:
Für das Bibliotheksverwaltungssystem werde ich zunächst eine gründliche Analyse der Anforderungen durchführen.
Hierbei werde ich festlegen, welche Funktionen und Ziele die Software erfüllen soll. Ein wesentlicher Aspekt ist auch,
die unterschiedlichen Akteure zu identifizieren, die die Software verwenden werden, um ihre Bedürfnisse und Anforderungen zu berücksichtigen.
Design und Datenstrukturentscheidung:
In diesem Schritt plane und entwerfe ich die grundlegende Klassenstruktur.
Dazu werde ich ermitteln, wie viele Klassen benötigt werden und welche Attribute und Methoden jede Klasse enthalten soll.
ich werde auch die Beziehungen zwischen den Klassen definieren(z.b Vererbung, Assoziation, etc..)
