Create a student registration class diagram for all requirement that contains at least 15 class, necessary relations and types. Include important attribute of class. Use three of the patterns in your class design using at least one creational, structural, and behavioral in an integrated way. (it should be written and show which patterns are used). The design should be homogenate. Excessive usage of any property type, object type, or function type is not suitable. For example, for creating 10 relations between classes, the number of relation types for aggregation, composition, etc. should be near to each other.
