RE: (ROSE) Cardinality

[Sandeep . Shrivastava]

Hi Compadre,   There are four type of relationships exits for the classes, they are following   Dependency: Relationship where one class depends upon another class for a particular service. Association: a structural relationship that describes a set of links - i.e., connections between objects. Generalization: specialization/generalization relationship. Objects of specialized elements are substitutable for objects of generalized element. Realization: One classifier specifies a contract that another classifier guarantees to carry out  - e.g., between interfaces and classes.   Hopes this answers your query...   Sandeep   -----Original Message----- From: Compadre [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 20, 2001 5:00 PM To: [EMAIL PROTECTED] Subject: (ROSE) Cardinality hi ALL, The cardinality between classes of OO model must be equal as cardinality of ER or are they totally diferent? Thanks.
