NoSQL databases are so called because they don't have the same rigid structure of SQL databases. There are also known as document databases as they can store unstructured data such as documents.

### Table storage
Table storage allows you to store semi-structured data. Table storage is actually a NoSQL database, so doesn't require a defined set of tables up front, but is designed to store data in one or more tables, with unique keys to define each row.

### Queue storage
Queue storage allows you to store messages of up to 64KB in size in a queue. You can add messages to the back of the queue, and read them off the front. Queues store messages indefinitely as long as there is still storage space, so allows messages to be stored long term. then read off when needed. For example, if you wanted to run a monthly job to process GPS data you could add it to a queue every day for a month, then at the end of the month process all the messages off the queue.
