John P. Mylopoulos is a Greek-Canadian computer scientist, Professor at the University of Toronto, Canada, and at the University of Trento, Italy.
Education
Born in Greece in 1943, Mylopoulos in 1966 received his Bachelor of Engineering from Brown University. In 1970 he received his Doctor of Philosophy from Princeton University under supervision of Theodosios Pavlidis with the thesis, entitled "On the Definition and Recognition of Patterns in Discrete Spaces.".
Career
He is known for his work in the field of conceptual modeling, specifically the development an agent-oriented software development methodology. called TROPOS. In 1966 he started his academic career as Assistant Professor at the University of Toronto, where he in 1971 he was appointed Professor in Computer Science. In 2009 he was also appointed Professor of Computer Science at the University of Trento. In 2012 he also received a Honorary Doctorate from the Rheinisch-Westfälische Technische Hochschule Aachen University in recognition of "his excellent and distinctive contributions on the methodology of conceptual modeling as a basis for databases, software technology and artificial intelligence, as well as its interdisciplinary applications.".
TORUS: Natural-language access to databases, which required the representation of the semantics of the data, and hence first led us to conceptual models of relational tables using semantic networks.
TAXIS: Programming language for data-intensive applications which supported classes of objects, transactions, constraints, exceptions and workflows, all orthogonally organized in sub-class hierarchies with property inheritance. TELOS: Representation language for knowledge of many different kinds of software engineering stakeholders, including application domain and development domain, which exploited meta-classes, and treated properties as object TROPOS: Applying the ideas of early requirements (goal orientation, agent dependence) to the entire range of software development, and expanding its scope to many topics, including security and evolution.
