Learning Goal: I’m working on a mysql question and need support to help me learn.

  1. Anser the questions:
    1. What is Generalization, Specialization and Aggregation?
    2. What is a many-to-many relationship? Give an example?
  2. A physician office wants to send reminders (using emails) to their patients. To do this they would like to use a database to keep track of which reminders are sent to which patients. A reminder has a reminder ID (RID), a subject (Subject), and a body (Body). A patient is identified by email address (Email) and patients data includes name and address. When a reminder is sent, the date (SendDate) is recorded.
    1. Give an ER diagram that completely describes the entities and relationships.
