Database Information
Learn about the structure of a database for an online store.
Imagine you visit an online store with a well-organized system. The homepage categorizes items by types such as electronics, clothing, and books. Each category further organizes products by brand, price, and ratings, making it easy to find what you're looking for without browsing through unrelated items. This requires a very well planned and thought out strategy to maintain and display all the necessary information in a concise manner.
In this course, we will be working on a model that simulates an online store database. This will help us to be consistent in learning SQL concepts with confidence to relate them with real life scenario. We'll go step by step to:
Understand the scenario of the online store database.
Get introduced to the main tables:
Categories,Products,Customers,Suppliers, andOrders.Recognize how these tables are interconnected to represent real-world data relationships.
Overview of the database
The database we’ll use to make our learning practical and relatable is modeled on an online retail store. It represents a typical e-commerce platform where customers can browse products, place orders, and receive shipments from various suppliers. This scenario allows us to explore real-world data management challenges, such as handling customer orders, tracking inventory, and managing supplier relationships.
To be precise, our database named OnlineStore is designed to handle:
Product catalog: A collection of products organized into categories for easy navigation.
Customer information: Details about customers who register and make purchases.
Supplier details: Information about suppliers providing products to the store.
Order management: Records of customer orders and transaction details.
