Database systems that don't use traditional SQL structure, designed for flexible data storage. Like having different filing systems optimized for different types of information.

They are not identical products: DynamoDB is a key-value and document database, Azure Cosmos DB supports multiple NoSQL models and APIs, Cloud Bigtable is a wide-column database optimized for large-scale low-latency workloads, and Oracle NoSQL Database Cloud Service provides key-value NoSQL capabilities. They all help applications store non-relational data at scale, but the best fit depends on data model, query needs, latency, and global distribution requirements.
