Reduce the space of memory IL. True/False questions Deeply nested classes can be difficulty to understand. (F.) Abstract is the determined examination of certain aspects of a problem The goal of abstraction is to link those aspect 1. 2. 3. s that are important for some purpose and 4. 5. suppress those aspects that are unimportant. Abstract is a fundamental human capability that permits us to deal with complexity. Class model describes behavior structure of objects and their relationships to one another 6. 7. 8. 9. 10. A link is a physical or conceptual connection among objects and is an instance of an I1. An aggregation is a description of a group of links with common structure and The content of a class model is a matter of judgment and is driven by the needs of an An object is a concept, abstraction, or thing with identity that has meaning for an A class describes a group of objects with the same attributes, behavior, kinds of An operation is a function of procedure that may be applied to or by objects in multiphe user application. relationships, and semantics. classes. aggregation semantics. 12. An association is a logical construct, of which a reference is a design alternative. 13. Multiplicity specifies the number of instances of on class that may relate to a single instance of an associated class. 14. An association class is an association that is also a class 15. An association class may have attributes, operation and participant in associations. 16. A qualified association is an association in which the objects in a "many" association end are partially or fully disambiguated by an attributed called the qualifier. 17. Generalization is an important construct for both conceptual modeling and implementation.
