About

Bernhard Thalheim is a foundational figure in conceptual modeling, database theory, and the philosophy of information systems. His work bridges rigorous formal foundations with practical design, most notably through his development of the Higher-Order Entity-Relationship Model (HERM), which extends traditional ER modeling to capture complex, nested structures and behavioral semantics. This contribution has shaped how databases are designed for advanced applications, from scientific data management to web information systems. Thalheim has also made significant contributions to the theory of normalization, schema evolution, and the interplay between databases and logic. His recent explorations into artificial intelligence, as seen in papers like "Artificial Intelligence Yesterday, Today and Tomorrow" (28 citations) and "About the Essence of Intelligence" (5 citations), reflect a career-long interest in the conceptual foundations of computation and intelligence. With hundreds of publications and thousands of citations, his work is a cornerstone for researchers in conceptual modeling, database design, and information systems engineering. Thalheim’s influence extends through his editorial roles and his mentorship of a generation of database theorists, making him a key architect of modern data management.
