Terry Halpin

Terry A. Halpin is an Australian computer scientist and professor VP of Conceptual Modeling at Neumont University, who is known for his formalization of the object role modeling notation.

Biography

Terry Halpin has received a BSc, DipEd, BA, MLitStud and PhD. He previously lectured at the University of Queensland, Australia.

After a lengthy career as an academic in computer science, which he combined with industrial work on database modeling, he moved to industry full-time, heading database research at Asymetrix Corporation, InfoModelers Inc., and Visio Corporation before its acquisition by Microsoft, where as Program Manager in Database Modeling, he worked on the conceptual and logical database modeling technology in Microsoft Visio for Enterprise Architects. After several years in industry, he has returned to academia in his VP position at Neumont University, where he is teaching curricula to facilitate application development using a business rules approach to informatics. [http://www.orm.net/halpin.html Terry Halpin] homepage at orm.net. Retrieved 1 Oktober 2008.] At Neumont Halpin is leading a team of developers in the creation of "Neumont Object Role Modeling Architect" (NORMA), an add-in for Microsoft Visual Studio 2005.

Halpin has been editor or reviewer for several academic journals and international program committees, has co-chaired several international workshops on modeling, and has presented at dozens of international conferences in both industry and academia.

Work

For many years, his research has focused on conceptual modeling and conceptual query technology for information systems, using a business rules approach.

Object-Role Modeling

His doctoral thesis formalized Object Role Modeling (ORM/NIAM). Object Role Modeling (ORM) is a powerful method for designing and querying database models at the conceptual level, where the application is described in terms easily understood by non-technical users. In practice, ORM data models often capture more business rules, and are easier to validate and evolve than data models in other approaches. [http://www.orm.net Object Role Modeling (ORM)] website.
