Subtype:
- Subtype is one type of entity which inherits the attributes from other entity.
- The subtype relationship is a grouping of entities type in single entity that shares the common attributes or relationships which are different from other grouping.
- It is related to an entity supertype, where the supertype entity has common characteristics and the subtype entity has the unique characteristics of each entity subtype.
