Webinar Shows In-Memory Database System Is Much More Than "Traditional" DBMS Deployed on a RAM-Disk
June 19, 2009 (PRLEAP.COM) Technology News
McObject's Webinar, "What Makes A Database System 'In-Memory'?" scheduled for June 25, tears apart the idea that In-Memory Database System (IMDS) responsiveness is equivalent to a conventional database deployed in memory, such as on a RAM-disk. Attendees will come away understanding the significant sources of overhead that burden any disk-oriented database management system (DBMS), even when that DBMS is held in RAM.A RAM disk, or RAM drive, is software that enables applications to transparently use memory as if it were a hard disk, usually in order to avoid physical disk access and improve performance. Applications such as telecom call routing have deployed on-disk database systems on RAM disks in order to accomplish real-time tasks.
But DBMSs deployed in this manner are still hard-wired for disk storage. Processes such as caching and file I/O continue to operate - even though they are redundant in this environment - and to drain performance.
An in-memory database system stores data in main memory, keeping all records available for instant access. IMDSs eliminate cache management, logical and physical I/O, as well as data duplication and transfer inherent in on-disk DBMSs. As a result, IMDSs will always turn in better performance.
"What Makes a Database System 'In-Memory'?" addresses common misperceptions surrounding IMDSs. Join noted author and database technology expert Steve Graves on Thursday, June 25 to gain a better understanding of IMDSs, which are used in real-time applications in a wide range of industries including aerospace, defense, telecommunications, networking, financial trading, industrial control and consumer electronics.
Other myths on the chopping block in this Webinar include:
Myth 1: On-Disks DBMSs Can Use Caching To Equal In-Memory Database Systems' Performance
Myth 3: By Using A Solid State Drive (SSD) For Storage, an On-Disk Database System Offers Performance Equal to an In-Memory Database System
Myth 4: 'Memory Tables', a Feature Offered By Some Conventional DBMSs, Are the Same as In-Memory Database Systems
