The Entity-Attribute-Value (EAV) model is a database design pattern that stores highly variable or sparse data in three columns:
| Column | Example |
|---|---|
| Entity | product_id = 123 |
| Attribute | color |
| Value | Midnight Blue |
Because new attributes don't require schema changes, EAV is popular for e-commerce or review data where every scraped product may carry different fields. When you feed your tables with information collected through Proxied 4G/5G proxies, EAV lets you capture every attribute—no matter how niche—without breaking the model.
