Object role modeling, a method for conceptual modeling.

Halpin's research interest is in the field of "conceptual modeling and conceptual query technology for information systems, using a business rules approach".

Reification is widely used in conceptual modeling.

Since 1979, an annual international professional conference on conceptual modeling has been held in different countries.

It is mainly used for conceptual modeling and metamodeling in the domain of software engineering and related domains.

Conceptualization from observation of physical existence and conceptual modeling are the necessary means human employ to think and solve problems.

Those weak links in the system design and development process can be traced to improper execution of the fundamental objectives of conceptual modeling.

As systems have become increasingly complex, the role of conceptual modeling has dramatically expanded.

With that expanded presence, the effectiveness of conceptual modeling at capturing the fundamentals of a system is being realized.

However, document engineering emphasizes the need for conceptual modeling of documents and processes at an implementable granularity.
