Pure Document Stores
Pure document stores are NoSQL databases that store data in flexible, schema-less documents, typically in formats like JSON, BSON, or XML. They are designed for high scalability, fast read/write operations, and handling semi-structured or unstructured data. Unlike relational databases, they do not enforce rigid table structures, allowing for dynamic and nested data models.
Developers should use pure document stores when building applications with rapidly changing data schemas, such as content management systems, real-time analytics, or e-commerce platforms with varied product attributes. They are ideal for scenarios requiring horizontal scaling, high performance on large datasets, and where data relationships are less complex or can be embedded within documents.
