Smooth Transition to Leverage the power of HANA without affecting existing infrastructure
This is just an extract from great lecture series (Chapter 05 - Foundation for New Enterprise Application Development Era) by Dr.-Ing. Jürgen Müller,
Chapter 5 is great initiative for HANA developers to quickly how HAN eliminates most of the tedious and time consuming processes we have been using.
This give great overview and explanation on how easy is to adapt power of HANA using
"Bypass Solution".
Different (before using HANA -In_Memory Database and After using HANA in-memory database)
Above illustration shows the conventional implementation of ERP systems which relies on 3rd party database systems. Key drawback of such architecture is being the presence of ETL and separation of OLAP engine , which handicaps the organizations real time reporting capability.
You could notice that HANA already helped to remove "Transformation" process of ETL activity by eliminating need for traditional info cubes. Bypass solution doesn't interrupt the usual operation of ERP system. new HANA -database will be updated using triggers programmed on traditional database to enable updated state of data.
Above picture shows the final state after complete transition, you could notice that OLTP & OLAP process takes place simultaneously.It is clear that future ERP systems will be on top of HANA architecture to leverage the power of in-memory database technology
Conclusion:
We could foresee promising future and demand for HANA Developers and they will be the game changers of Enterprise application era.
So Learn and develop our little girl HANA to reach her full potential
