Answer 1

In summary, to create an EER diagram in MySQL Workbench, one would define entities for products, categories, customers, addresses, countries, members, and groups, and establish necessary relationships such as one-to-many between customers and addresses, one-to-many between categories and products, and many-to-many between members and groups.

Step-by-step explanation:

To create an EER diagram in MySQL Workbench for the stated requirements, you would follow these steps for each part of the question:

1. Create entities for Products, Categories, Customers, Addresses, Countries, Members, and Groups.
2. For the Product entity, include attributes such as product name, description, and price and create a one-to-many relationship between Categories and Products since each product belongs to one category, but each category can have multiple products.
3. For the Customer entity, include the email address, first name, and last name as attributes and address the requirement that each customer can have two or more addresses by creating a one-to-many relationship between the Customer entity and the Address entity.
4. Create a separate entity for Countries to ensure the country name is stored in one place only, and then relate this to the Address entity.
5. For the Membership tracking, you would need to create many-to-many relationships between the Member and Group entities for members who can belong to any number of groups and vice versa.

By using MySQL Workbench, you can create these entities and relationships visually, and it will generate an EER diagram that you can use to understand the structure of your database and to further create your SQL schema.
