Document Databases

Flexible, schema-less databases that store data in JSON-like documents, perfect for modern applications

What Are Document Databases?

Document databases store data in flexible, JSON-like documents instead of rigid table structures. Each document can have its own structure, making them ideal for applications with evolving data models.

Unlike relational databases that require predefined schemas, document databases allow you to store complex, nested data structures naturally, making development faster and more intuitive.
