The document describes a database for a new online toy store launching a big weekend sale. It includes a scenario describing excited kids awaiting new toys for the holidays and the store's sale offer. An entity-relationship diagram shows users, products, payments, orders, and categories. Finally, the relational schema defines tables for users, categories, products, payments, orders, and relationships between them to support the store's operations and sale.

As the Eid is near kids are really excited about the holidays but they are
mostly excited for their new toys that they will get this time. And as a matter
of fact there is a new big online toy store for kids while it’s preparing itself in
the mean-time. The toy store will arrange a big sell weekend offer for their
users (user_id, user_gender,gold_user,platinum_user,admin) to buy toys
where they can choose products (product_id,toys,amount). Products are
organized by category (product_brand, for_male, for_female) based. Users
can purchase products through payment (product_id,user_id, amount,method
) by ordering(ordered_things,user_id,user_gender). So that’s why they are
organizing such a big weekend offer just to kick-off their business with a good
profit.
