Abstract
In several relational systems such as VERSO, elementary processing of relational operations (filtering) is relegated to a processing unit close to the mass storage device.
The work presented below addresses the problem of choosing among two competitive approaches for implementing filtering:
-
(i)
the database machine approach: filtering is implemented by means of a dedicated hardware,
-
(ii)
the software approach consists in writing code to be run on a regular “off-the-shelf” microprocessor.
Both approaches have been experimented in the VERSO system. The objective of this paper is to compare the Selection/Projection response times provided by both the hardware filter and the software filter.
