in-memory database

Storing the contents of a database in main memory rather than on disk. Since memory (RAM) is considerably faster than a hard disk or even a solid state disk, complex decision support queries can be satisfied much more rapidly, and high-end computers can be configured with terabytes of memory. However, memory can fail due to power outages and component breakdown; therefore, snapshots are taken periodically and saved to permanent disk storage. See SAP HANA and RAM disk.

In Time, It Will Merge
At some point in the future, perhaps 10 or 20 years from now, main memory and disk storage will merge into one "memory/storage" pool as all storage will be addressable like DRAM memory but will be non-volatile. See future memory chips.

A Geordie Greeting WHEN I came to live in the North East The strangest thing occurred It seems I was already known And I found this quite absurd It's not as if I was well known I'm just a quiet little mouse But something odd was happening As I said to my puzzled spouse Everyone I met was friendly And I happily chatted away To any stranger who spoke to me And passed the time of day But still it was unsettling How could it possibly be That I did not know anyone But everyone knew me And then the wheels began to turn In my memory database The Catherine Cookson books I'd read And it all fell into place People weren't calling me by name which is Pat, How could I forget - They were greeting me the North East way They were saying, 'Hello Pet!'
