Photorefractive volume holographic memories can be used to realize fast data searches because they allow associative data recall. We have developed a prototype of a volume holographic database system and examined its potential use for a number of applications in a multimedia environment, including database management, video indexing, and interactive video. The experimental results presented in this paper demonstrate that associative recall is possible with any combination of digital (binary) and analog (image) data.
