How do you make an er diagram for virus blocking?

Answer 1

To create an Entity-Relationship (ER) diagram for virus blocking, start by identifying the key entities involved, such as "User," "Device," "Virus," and "Blocking Rule." Define the relationships between these entities, for example, a "User" can have multiple "Devices," and each "Device" can have multiple "Blocking Rules" to prevent specific "Viruses." Specify attributes for each entity, like "User ID," "Device ID," "Virus Name," and "Rule Type." Finally, use a diagramming tool to visually represent these entities, relationships, and attributes, ensuring clear connections and cardinalities.
