database machine

   Also found in: Acronyms, Wikipedia 0.06 sec.

database machine

A computer system designed for database access. Database machines never caught on until the early 1990s when massively parallel processors (MPPs) from companies such as Teradata (acquired by AT&T), nCube, Thinking Machines and Kendall Square Research, proved the concept. Using hundreds and even thousands of microprocessors with database software designed for parallelism, database machines can scan large files much faster than a mainframe.

Dramatic Improvements
Huge performance increases have been documented. For example, a large financial organization reduced 30 days' worth of month-end analysis and reporting to a single day. In other cases, queries have been speeded up by a factor of 100. Database machines using MPP architecture are expected to grow in popularity for decision support systems in large organizations.


(hardware)database machine - A computer or special hardware that stores and retrieves data from a database. It is specially designed for database access and is coupled to the main (front-end) computer(s) by a high-speed channel. This contrasts with a database server, which is a computer in a local area network that holds a database. The database machine is tightly coupled to the main CPU, whereas the database server is loosely coupled via the network.

Once the database is able to handle more record updates, the software initiates the next batch of updates, all while monitoring database performance to make sure it never overloads the SQL server or any other database machine.
DDP allows top-tier carriers to maintain large, distributed network records on a single Xng database machine, lowering the total cost of ownership (TCO) of the system, while securely providing highly granular access to network information based on criteria as diverse as geographic region, customer and equipment age.
Furthermore, with rating processes running on separate machines from the main database, the database machine can be smaller, with correspondingly lower database license costs.
