Azure DocumentDB and Azure Blob Storage

Question

I'm using azure document db in my ASP.net MVC application.And currently I'm having 2 collections in it which are Employees and Tasks. Currently everything is working fine with document db operations.

But I couldn't find a way to upload multiple images(not multiple images at once ) against a document. eg: assume I need to store 2 employee pictures against a single employee document.

I've read about the azure blob storage and think I can use it for the file uploads.But the thing that I can unable to clarify is how to keep the references of the uploaded files in each employee documents.

Is there any way to do that?

Each blob in blob storage is accessible via a URL. What you could do is save these URLs along with the document. For example, your Employee JSON could look like:

Employee = {
  'Id': '0001',
  'Name': 'Some Name',
  'Pictures': [
    'https://account.blob.core.windows.net/container/image1.png',
    'https://account.blob.core.windows.net/container/image2.png'
  ]
}

Other thing you could do is look at Attachments in DocumentDB.
