Not Only

SQL

• The ability to store & retrieve great quantities of data is important

• Storing relationship between the elements are not important

• Dealing with growing lists of elements: Twitter posts, internet server logs, Blogs

• The data is not structured or the structured or the structure is changing with time

• Prototypes or fast applications need to be developed

• Constraints and validations logic is not required to be implemented in database

Hbase NoSQL Database System Architecture
