Hi,
I have the following question about HANA and i cannot find any answer on any blogs :-
1) If the crux of Hana speed is all about running on RAM memory instead of a physical hard disk, why can’t all the other competitors do the same to build their database on RAM instead of hard disks? What is stopping them from doing so? I have to ask this because HANA's speed is not about its secret logic or anything like that it is purely because of the fact that RAM memory is used to hold the entire database.
