Title: Daniela D. Florescu and Her Contributions to XML Query Processing

Introduction

Daniela D. Florescu is an inventor associated with Palo Alto, California, and Bea Systems, Inc. Her patent work addresses computer language systems, including methods for processing XML queries and representing data types. The supplied information lists 3 patents.

Latest Patents

One of Florescu’s latest patents, “Systems and Methods for Implementing an XML Query Language,” describes an implementation of the XQuery standard. The approach can use a token-stream representation to process large XML documents without first loading each entire document into memory. It also describes a streaming XQuery engine and algorithms and rewrite rules that can transform queries into forms suitable for processing XML streams. The patent further discusses an XML Schema-based type system and execution contexts that include variable bindings, namespaces, operators, and default parameters.

Another patent, “Systems and Methods for Implementing a Computer Language Type System,” concerns implementing type systems that support subtype relationships and nested types. It describes augmenting finite-state automata algorithms with additional transitions for subtype symbols. The approach compares data types by considering both their names and their contents.

Career Highlights

Florescu’s listed inventions focus on foundational software technologies: querying structured XML data and implementing computer-language type systems. These areas are relevant to processing large documents and representing relationships among data types.

Collaborations

The supplied information identifies Paul J. Lucas and Fabio Riccardi as Florescu’s coworkers. It also associates her with Bea Systems, Inc.

Conclusion

Daniela D. Florescu’s patent portfolio reflects work on XML query processing and type-system implementation, with an emphasis on efficient data handling and formal methods for representing types.
