PREDATOR : An OR-DBMS with Enhanced Data Types

Summary: PREDATOR is an object-relational DBMS with Enhanced ADTs (E-ADTs) that add semantics to rich data (images, audio, video, GIS) to boost performance. Demonstrates SQL querying, content-based indexing, path-indexed retrieval, E-ADT optimization, and a WWW/Java UI. (summarized by gpt-5-nano on Feb 09 2026)
