Explanation of Solution
Cardinality:
Connecting lines among the entities will illustrate the relationships of entities in the ER diagram.
- “Cardinality” states that how many occurrences of an entity relate to one occurrence of other entity.
Crow’s Foot symbols and its cardinality:
The following table illustrates the different connectivity and participation combinations which are maintained by the Crow’s Foot notation:
| Notation | Cardinality | Description |
| (0,N) | Zero or more instances | |
| (1,N) | One or more instances | |
| (1,1) | One instance | |
| (0,1) | Zero or one instance |
Cardinalities for given ERD:
The following figure illustrates the cardinalities for each relationship in given ER diagram:
