The slowest aspect of a database is reading and writing to disk. Using Sybase ASE in-memory database can improve your performance by eliminating the overhead associated with reading and writing to conventional disks.

Getting extreme performance out of your system is important.  As the number of customers you have grow and the load on your database increases you need to make sure you still deliver your services at the same speed or faster to be competitive.  Sybase Adaptive Server Enterprise (ASE) In-Memory databases make it easy to achieve extreme performance.

In order to achieve performance a system needs to be able to manage inserting, updating and deleting data with a high degree of throughput.    To meet the throughput demand databases in memory remove the need to write to physical disks.  Now that we have 64-bit machines and the price of memory is coming down it is not uncommon to have machines with massive amounts of memory. 

ASE in memory databases reside completely in memory and therefore have no disk footprint.   Since the data of these databases are in memory a lot of complex processing related to physical disks can be eliminated.  There are two flavors of in memory databases: fully and relaxed.  Relaxed databases can be persisted on disk if a polite shutdown occurs.

Sybase ASE in memory databases provides seamless integration between traditional databases and in memory databases. For applications that need fast performance and are not constrained by traditional transaction based processing rules can take advantage of the benefits of in memory databases.  Sybase ASE in memory databases provides a low cost, low complexity solution to high throughputs when processing large volumes of data.
