Study Notes
UML Notation and Class Diagrams in Systems Analysis and Design
- UML notation for multiplicity represents the relationship between instances of different classes
- Domain model class diagrams for a bank with many branches and course enrollment at a university are illustrated
- An association class is used in a many-to-many association to remember attributes such as grades in a refined course enrollment model
- The key for an association class is formed by concatenating the keys of the attached classes
- In a hospital registration system, each ward has many medical histories, and each patient has many visits associated with a ward
- The concept of generalization/specialization involves hierarchical relationships where subordinate classes are special types of superior classes
- Inheritance in generalization/specialization allows subclasses to inherit characteristics of the more general superclass
- Abstract classes, concrete classes, and their attributes are explained in the context of inheritance for RMO and a bank with special types of accounts
- Whole-part relationships, such as aggregation and composition, are described with examples like a computer and its disk storage devices
- Aggregation and composition are subsets of association, each with distinct characteristics
- Notation for aggregation with a diamond symbol and the possibility of multiplicity symbols for whole-part relationships are highlighted
- The text is from "Systems Analysis and Design in a Changing World, 7th Edition - Chapter 4" by Cengage Learning, 2016
