Database Scales With Call Volumes

TimesTen Inc. this week will unveil an upgrade to its in-memory database that boasts enhancements in performance, scalability and ease of integration with larger relational DBMSes.

Version 5.0 of TimesTen Real-Time Event Processing System, available now, adds support for Intel Corp. Itanium 2-based servers running Red Hat Inc.'s Red Hat Linux, officials said.

For the upgrade, the Mountain View, Calif., company tweaked concurrency--the ability for multiple users to access and share data simultaneously--to improve performance, officials said.

Instead of requiring data managers to use locks to prevent multiple users from changing data at the same time, TimesTen 5.0 uses a multiple-version model where users can query and read data at the same time that the system processes updates.
