What is HANA Technology?

It is the Combination of Multi-Core Parallelism , 

Data locality in memory & Columnar Structures

Columnar database has unique advantages:

1. Improves Analytic Performance
2. Multicore Processing
3. Larger availability of DRAM

Hana supports both Row and Column stores

               Hana is not completely a new technology.Rethought and Re factored everything on Hana platform,when i first heard about hana i thought it is a database like oracle, microsoft sql server...but it is more than a database.It becomes a Platform which makes me surprising because when i know about hana people used to talk about memory and Sql, now programmers can write code, data warehousing and modelling consultants can model and run reports faster and the people who has knowledge on sql can learn easily, etc.There are so many things which can be done in HANA PLATFORM...Decide Yourself and move on different paths in HANA..

only limitation is our IMAGINATION...
