Entity - Relationship Diagram (ERD) for Safe and Healthy Kids Template

Designed with EdrawMax, this template is an Entity - Relationship Diagram for the “Safe and Healthy Kids” project. It depicts multiple entities such as “school_admin,” “school_bus,” “driver_authorized_on_route,” etc., along with their attributes like primary keys (PK) and foreign keys (FK). The diagram uses diamond - shaped symbols to show relationships like “One to Many” and “Many to Many” between these entities. For example, the “school_bus” entity has a relationship with other entities related to bus operations and safety. This ERD serves as a crucial tool for database design in the context of child health and safety, helping to structure data and understand the connections between different aspects of the initiative.
