What is the diffrence between SAP HANA and SAP R/3?
R/3 stand for real time data processing and 3 stand for 3 architecture layer (presentation layer, application layer & development layer). SAP R/3 provide the capability to manage financial, asset, and cost accounting, production operations and materials, personnel, plants, and archived documents. The R/3 system runs on a number of platforms including windows and other client/server model.
SAP HANA is an in-memory data platform that is deployable as an on-premise appliance, or in the cloud. It is a revolutionary platform that’s best suited for performing real-time analytics, and developing and deploying real-time applications. At the core of this real-time data platform is the SAP HANA database which is fundamentally different than any other database engine in the market today
Whenever companies have to go deep within their data sets to ask complex and interactive questions, and have to go broad (which means working with enormous data sets that are of different types and from different sources) at the same time, SAP HANA is well-suited. Increasingly there is a need for this data to be recent and preferably in real-time. Add to that the need for high speed (very fast response time and true interactivity), and the need to do all this without any pre-fabrication (no data preparation, no pre-aggregates, no-tuning) and you have a unique combination of requirements that only SAP HANA can address effectively. When this set of needs or any subset thereof have to be addressed (in any combination), SAP HANA is in its elements.
In a very high level.
Sap r/3 is a enterprise resource planning (erp) system. It follows the traditional 3-tier architecture (presentation, application, and database).
Sap Hana is a platform ( includes multiple components – database, trex, spatial, graph, calculation, extended application-xsc/ Xsa, embedded data replication tools, etc)
You can also run R/3 on SAP Hana.

SAP HANA is a cloud based application from SAP. It has propelled SAP to the cloud ecosystem that takes the desktop based R/3 to the mobile devices of the users.
HANA has just 2–3 tables in its architecture whereas there are thousands of tables in R/3. Such a massive data is compressed almost 8 times in HANA, thereby improving speed and efficiency of the system.
