Case Study - Dicoding Collection

1. Background

Dicoding Collection or often abbreviated as DiCo is a company specializing in fashion. They produce various fashion items and sell them through online platforms.

As a contemporary company, DiCo realizes how crucial data is for the growth of a business. Hence, they stored all the sales history along with information related to products and customers in a database. This database consists of four tables, including customers, orders, products, and sales.

  • Customers table: this table stores various customer-related information, such as customer_id, customer_name, gender, age, home_address, zip_code, city, state, and country.
  • Orders table: this table stores various information related to an order consisting of order_id, customer_id, order_date, and delivery_date.
  • Products table: this table contains various information related to a product, such as product_id, product_type, product_name, size, color, price, quantity, and description.
  • Sales table: this table contains detailed information related to sales, such as sales_id, order_id, product_id, price_per_unit, quantity, and total_price.
