Introduction of Class Diagram (CD) � Visualisasi struktur kelas-kelas dari suatu sistem. � CD adalah blueprints dari sebuah sistem atau sub sistem � CD memperlihatkan hubungan antarkelas dan penjelasan detail tiap-tiap kelas di dalam model desain dari suatu sistem. � Selama proses analisis, CD memperlihatkan aturan dan tanggung jawab entitas yang menentukan perilaku sistem. � Selama tahap desain, CD berperan menangkap struktur dari semua kelas yang membentuk arsitektur sistem yang dibuat � CD juga merupakan fondasi untuk component diagram dan deployment diagram.

What is a Class generally ? �A set, collection, group, or configuration contai ning members regarded as having certain attrib utes or traits in common; a kind or category. [http: //www. thefreedictionary. com/class] � Biology A taxonomic category ranking below a phylum or division and above an order. See Table at taxonomy.

Class in UML �A class diagram is an illustration of the relationships and source code dependencies among classes in the Unified Modeling Language (UML). �In this context, a class defines the methods and variables in an object, which is a specific entity in a program or the unit of code representing that entity. � Class diagrams are useful in all forms of objectoriented programming (OOP). The concept is several years old but has been refined as OOP modeling paradigms have evolved.
