Storing Data in NoSQL Databases
Learn when and how to persist scraped data in document-oriented NoSQL stores like MongoDB for flexible, schema-light storage.
When SQL Is Not Enough
Scraped data is often irregular: different pages yield different fields, nested structures, and evolving shapes. Rigid SQL schemas can be painful here.
NoSQL document databases store flexible JSON-like records, making them a natural fit for messy web data.
Documents and Collections
In a document store like MongoDB:
- A document is one JSON-like record.
- A collection groups related documents (like a table).
- Documents in one collection need not share the same fields.
