Case Study:
The Fragrance Flowers Group operates extensively in the Australian flower industry. They are a multi-generational family business running for last 50 years focussing on providing everyday fresh and quality flowers to customers through different cities in Australia. They also provide the option to add accessory items such as teddy bears, chocolates or a vase along with the flower purchase. Recently they are planning to replace their current manual system by designing a new database system that will make the online flower ordering experience more convenient and hassle-free.
A simplified database should support procedures such as checking the inventory of all components for a particular arrangement in different store locations, determining popular items, fulfilling customer needs more efficiently, and allowing staff to generate customised reports as requested by the management. To support these functionalities the database should contain data about a particular store, customer, order, flower arrangements components, and accessory items.
The following list describes the data requirements in more details.
Customer data includes unique customer number, first name, last name, email, phone, and city. One customer can place one or many orders.
Order data includes unique order number, order description, order month, order year, order type, order total and store details (number, city, phone and manager) where that order is placed. An order can include one or many order items. Orders can be of three types - Online, phone, and in-person.
Order Item data includes various items purchased by the customer for a specific order. It can store information regarding order number, item (Flower arrangement) along with the qty of that item purchased.
FlowerArrangement information may include unique arrangement Id, name, style, occasion, and price. A store can sell specific types of flower arrangements.
Customers can buy flowers with different arrangements along with a number of accessories. Accessory information includes accessory id, name, and price.

Sample data for the proposed database is provided below:
