NoSQL

Types of NoSQL databases

key-value

• An associative array
• Single key lookup (very fast)
• Slow to search values
• examples: Redis and CouchDB

Column Store

• Orders by columns instead of rows
• Reads faster than Row Store
• Writes slower

Graph Stores

• stores as edges and vertexes
• eg. social networks

Multi-Model DB

• combine multiple storage models
• often Graph and something else

Document Store

• documents can be in JSON
