This document discusses noSQL databases and provides an overview of different data models including key-value, column-based, document-based and graph databases. It outlines characteristics of each model such as being distributed, using RAM for durability and being fault tolerant. The document encourages using the right data model and architecture for the job and being polyglot by using multiple databases together.

• Hierarchical (IMS): late 1960’s and 1970’s
• Directed graph (CODASYL): 1970’s
• Relational: 1970’s and early 1980’s
• Entity-Relationship: 1970’s
• Extended Relational: 1980’s
• Semantic: late 1970’s and 1980’s
• Object-oriented: late 1980’s and early 1990’s
• Object-relational: late 1980’s and early 1990’s
• Semi-structured (XML): late 1990’s to late 2000’s

“A Bigtable is a sparse, distributed, persistent multi-dimensional sorted map.The map is
indexed by a row key, column key, and a timestamp; each value in the map is an
uninterpreted array of bytes.”
