SAP BW on HANA - HANA Basics
HANA database takes advantage of in-memory processing to deliver the fastest dataretrieval speed, which is enticing for organizations struggling with high-scale online transactions or timely forecasting and planning.
Disk-based storage is still the enterprise standard and the price of RAM has been declining steadily. Thus, memory-intensive architectures will eventually replace slow, mechanical spinning disks and will lower the cost of Data storage.
In-memory column based storage provides data compression up to 11 times, reduces the space to store huge amount of data.
The speed advantages offered by RAM storage system are further enhanced by the use multi-core CPU’s multiple CPUs per node and multiple nodes per server in the distributed environment.
