### Presentation Entity-Relationship Diagram (ERD) for Problem 2 #### Overview: The figure illustrates an Entity-Relationship Diagram (ERD) for managing presentations and attendees. This database structure is divided into three main entities: Presentation, Registration, and Attendee. Each entity has specific attributes and keys that uniquely identify records and define relationships between the entities. #### Entities and Attributes: 1. **PRESENTATION** - **Primary Keys (PK):** - `Pres_SessionNum`: System-generated number. - `Pres_Order`: Number indicating the order of the presentations during the session. - **Attributes:** - `Pres_Date`: The date the presentation is scheduled to be given. - `Pres_Room`: The room in which the presentation will be given. - `Pres_Title`: The title of the presentation. - `Pres_AuthorID`: System-generated number assigned to presentation authors. - `Pres_FName`: The first name of the presentation author. - `Pres_LName`: The last name of the presentation author. 2. **REGISTRATION** - **Primary Keys (PK), **Foreign Keys (FK1, FK2):** - `Pres_SessionNum`: (FK1) Links to Presentation. - `Pres_Order`: (FK2) Links to Presentation. - `Att_Num`: Links to Attendee. - **Attributes:** - `Reg_Date`: The date the attendee registered. 3. **ATTENDEE** - **Primary Keys (PK):** - `Att_Num`: System-generated number. - **Attributes:** - `Att_FName`: The first name of the attendee. - `Att_LName`: The last name of the attendee. - `Att_Status`: Whether or not the attendee has paid the registration fee. #### Relationships and Constraints: - The **PRESENTATION** entity is linked to the **REGISTRATION** entity via the composite primary key (`Pres_SessionNum`, `Pres_Order`). The `REG_DATE` attribute in the **REGISTRATION** entity records the date the attendee registered. - The **REGISTRATION** entity is linked to the **ATTENDEE** entity through the `Att_Num` attribute, establishing which attendee has registered for which presentation. This ERD is crucial for managing the scheduling, authorship, and attendance of presentations in an organized manner. It ensures data integrity and facilitates efficient
