Modern Applications produce and consume incredibly high volume of data

Users today expects near instantaneous response times

Applications Database models are no longer fixed and evolve continuously

What is Azure DocumentDB?

It is a fully managed, highly scalable, queryable, schema-free document database, delivered as a service, for modern applications.

Provides a client-side logical representation of the Azure DocumentDB service

The method CreateOrGetDatabase check if the database already exists, if not, it will create it and return an instance of the database

A document collection is a named logical container for documents. 

The method CreateOrGetCollection returns the collections if it already exists, else it will create the collection.

To save documents, the method CreateDocumentAsync is used which creates a document as an asynchronous operation.

Both SQL and LINQ can be used to retrieve data from DocummentDB using the CreateDocumentQuery method.

You first need to get the document to update, make the changes and replace the document using the ReplaceDocumentAsync mthod

Get the required document and delete it using the DeleteDocumentAsync method

Operations

Provides a client-side logical representation of the Azure DocumentDB service.
