In-memory database
Traditional disk resident database
holds data in disk.
In-memory database management
systems assume that the entire data
are resident in main memory.

Why is in-memory DB possible?
Answer: Moore’s law
Intensity of semiconductors are
doubled every 18 months.
1975, Super computer “Cray 1” have 1MB memory capacity
2012, Terabyte-scaled main memory is now available
Performance?
SAP In-Memory Appliance software (SAP HANA) easily handles 10,000 queries per hour against 1.3 terabytes of data and returns results within seconds
