Description
Summary:The PREDATOR is an object-relational database management systems, developed at Cornell University, which uses a novel enhanced-abstract data types (E-ADT) technology. E-ADTs add semantics to the complex data types, resulting in dramatically improved performance while retaining the extensibility of the database system. The PREDATOR's feature includes: standard relational query processing capability through sequential query languages SQL queries; extensibility with complex data types; content-based feature extraction, indexing and retrieval using path indexes; extensible optimization of E-ADT expressions by reordering and merging; and World Wide Web/Java-based user interfaces that supports extensible querying and display mechanisms.
