In advanced database management systems, Generalization and Aggregation are two important concepts that deal with the abstraction of data in Object-Oriented Database Management Systems (OODBMS) and Entity-Relationship (ER) models. Both concepts help in organizing data more efficiently and simplify the relationships between various entities.

Generalization

Generalization is a process in database design where two or more lower-level entities (subclasses) are combined into a higher-level entity (superclass) that holds the common characteristics of the lower-level entities. This is similar to abstraction, where common properties of the subclasses are abstracted into the superclass.

For example, if we have two entities like Car and Truck, both may have common attributes such as ___ _______ ___ _____ ___ _____ ____ ________ ____.
____ ____ ________ ____ ________ ______ ___ __________ __________ _____.
_____ _______ ________ ______ _____ ____ _________ ______ _________ ______ ___.
_____ ____ ______ ______ _______ ____ _____ _______ ________.
