Oracle8 Visual Information Retrieval Cartridge User's Guide
Release 1.0.1






Prev Next


This guide describes how to use Oracle8 Visual Information Retrieval Cartridge. This cartridge, based on technology licensed from Virage, Inc., extends the capabilities of Oracle8 Image Cartridge by allowing content-based retrieval of images.

Visual Information Retrieval Cartridge requires Oracle8 Enterprise Edition. Oracle8 and Oracle8 Enterprise Edition have the same basic features. However, several advanced features, such as data cartridges, are available only with the Enterprise Edition, and some of these features are optional. For example, to extend Visual Information Retrieval Cartridge, you must have the Enterprise Edition and the Objects Option.

For information about the differences between Oracle8 and the Oracle8 Enterprise Edition and the features and options that are available to you, see Getting to Know Oracle8.
