Redis Product Catalog

Product Catalog Use Case

In the last session several common Redis use cases were discussed. Now, lets consider using Redis as our primary database for a product catalog for a new online store. It will need to store product details including a name, description, vendor, price, main category and some images.

Requirements:

Product information stored in the database should include: name, description, vendor, price, category, images associated with that product.
Ability to create/update/delete product details
Ability to find product by ID
Ability to find products in category X
Ability to find product by its name or part of its name

Logical Data Model:

The logical data model is separate from the DBMS being used. It defines the structure of data elements and to set relationships between them.

Product Image
- Id: Number
- Value: Binary
Product
- Id: Number
- Name: String
- Description: String
- Vendor: String
- Price: Number
- Currency: String
- MainCategory: Category (1)
- Images: Image (0..n)
Category
- id: Number
- Name: String
- Products: Product (0..n)
