SAP HANA having a excellent architecture.It also serves as best database alternative.It Drives SAP future more towards prominently and sophisticated.
The biggest question for many number of SAP customers and variety of clients is whether they can replace their underlying Relation data base system with HANA.
For this SAP customers should understand and evaluate the roadmaps accordingly as the SAP HANA is a crucial and critical technology.
Why SAP HANA FAST:
For Inmemory database management systems(IMDBs),They store data directly on to the main memory of the computer.In that, memory resident data will have a backup copy at disklevel and the primary copy will be stored permanently.So IMDB s have faster access and response times at system based disk optimization levels.because of this we can provide the report informations very fastly in a range of nanoseconds.
At this context IMDB play a significant role as its a dealing of highere database volumes so ultimately we need fast response times and good real time streaming.
Also if we observe the HANA road map/arcgitecture In memory computing is the important component.
Note: Plesae make a note that HANA IS NOT AVAIABLE CURRENTLY FOR IMMEDIATE RDBMS REPLACEMENT FOR SAP-BUSINESS SUITE.aT THE SAME TIME HANA IS GROWING DRASTICALLY FOR ALL SAP/NON SAPBUSINESS SUITE MODELS.
