Column database - ANSWER A NoSQL model of a database that stores data in tabular
format using columns and rows.
Key-Value database - ANSWER A NoSQL model of a database that uses keys or unique
identifiers to store data as key-value pairs wherein the value portion is indecipherable to
the DBMS
Document Database - ANSWER A NoSQL model of a database that stores data in
key-value pairs wherein the value portion is made up of a tag-encoded document.
Documents wrap up and encode data-or information-in some kind of standard format or
encoding. Encodings currently in use include XML, YAML, and JSON, as well as binary
forms such as BSON.
Documents are identified in the database by a unique key representing that document.
One of the other defining characteristics of a document-oriented database is that in
addition to the key lookup performed by a key-value store, the database also offers an
API or query language that retrieves documents based on their contents.
Different implementations offer different ways of organizing and/or grouping
documents:
Collections
Tags
Non-visible metadata
Directory hierarchies
Graph database - ANSWER A NoSQL database model that is based on graph theory and
will store data on relationship-rich data as a collection of nodes and edges.
