Hosted Document databases

Question 1

What are document databases?

Answer 1

They expand on the basic idea of key-value stores where “documents” are more complex, in that they contain data and each document is assigned a unique key, which is used to retrieve the document.

Question 2

What are document databases designed for?

Answer 2

These are designed for storing, retrieving and managing document-oriented information, often stored as JSON. Each document can contain different types of data. Groups of documents are called collections. Each document in a collection can have a different structure.

Document databases have a flexible schema as defined by the document contents.
