Abstract
This paper presents a 3-D optical database machine that enables the parallel implementation of relational database operations. The basic data element in the proposed system is a 2-D data, page. The data pages are stored in a page-oriented optical mass memory, and processed by an 2-D optical content addressable memory (2-D OCAM) in parallel. A 2-D OCAM enables the comparison of a 2-D search page with a 2-D data page in parallel. Given a search page and a data page of size n × m bits, a 2-D OCAM can perform n 2 × m bit comparisons in single step (if n=512 and m=256, then n 2 × m = 671, 108, 864).
