Step 1: Defining introduction
The SQL queries for creating the tables and to store atleast 5 records in each is given below.
Before that let's organise the data first.
So, the given tables (entities) are -
- Author
- Book
- Customer
Here, the entity Author will be created first as it does not have any dependency on other tables (no foreign key attribute). The second table that will be created is Book because, the entity Customer depends on the entity Book. And the third entity to be created will be Customer.
