Create an ERD based on the Crow's Foot notation, using the following requirements (business rules):

1) An INVOICE is written by a SALESREP. Each sales representative can write many invoices, but each invoice is written by a single sales representative;

2)The INVOICE is written for a single CUSTOMER. However, each customer can have many invoices;

3) An INVOICE can include many detail lines (LINE), each of which describes one product bought by the customer;

4)The product information is stored in a PRODUCT entity;

5)The product's vendor information is found in a VENDOR entity.

Note: Follow the attached example of Tiny College ERD in Lecture 4 to draw the ERD. Make sure to do the following:

1) (5pts)name each relation properly and mark the cardinalities in each relation;

2) (5pts)identify the primary key and foreign key(if there is any) for each entity;

3) (10pts) use the correct notation for entities and give 2 or 3 attributes for each entity (you are free to choose the attribute names)
