WHY I CHOOSE NOSQL DATABASE?
Your data is high volume and low value and your application schema is dynamic then you choose NoSql database.
Why I Choose ORACLE Nosql DATABASE?
Oracle Nosql database is key-value database. Nosql written in JAVA. Good Scalability,load Balance and availability features.
Oracle Nosql database is easy install,configurable consistency and general purpose database.
Nosql database has Master nodes,replica Nodes,Kvstore and nosql apllication drivers.

Sample Application.
Credit Card Approval Application:
Credit card approval application data is high volume, RESPONSE TIME should be VERY FAST.
Why we choose Nosql?

Above mention example we design
Major key : Card Number
Minor key: Approval status
