Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements.
There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.

- Please written by computer source Part I - Modeling You are building a database for a comic book store customer management system. Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted.
