Mapping ER diagram to table
A database that conforms to an ER diagram can be represented by a collection of table in the relational system.
1. Regular Entity
2. Attributes
3. Relationship
4. Weak Entity
5. Subtype & super type
1. Regular Entity You will recall entity are dependent, they can exist in isolation, independent of any other blocks of database. Each regular entity maps to table.
WE ALWAYS GET PUZZLED IN DIFFERENT WORDS BUT WITH THE SAME MEANING.
