Data stored as collection of documents

Typically JSON (Javascript Object Notation)

Be careful with formatting (name/value pairs, commas etc)

address - Child Object - {}, socialProfiles - Array - []

Documents are retrieved by unique id (called the key)

Typically, you can define additional indexes

Documents don't need to have the same structure

No strict schema defined on database

Apps should handle variations (application defined schema)

Typically, information in one document would be stored in multiple tables,

if you were using a relational database

Use cases: Product Catalog, Profile, Shopping Cart etc

Managed Services: Azure Cosmos DB SQL & MongoDB API,

Amazon DynamoDB, Google Cloud Datastore
