Determining the relationship types that are relevant to an information system is one of the most important tasks in conceptual modeling. In this chapter, we study the nature and general characteristics of a relationship type.

Disparities in Tobacco Use and Lung Cancercial relationship, an . relationship, between entity types (and, in general, between concepts). . relationships are constraints. Entity types and their . relationships form a network structure called a taxonomy. Taxonomies are a very important part of conceptual schemas, and the objective of this chapter is to study them.

The Psychodynamic Assessment of Outcome,on and use of meta-metaschemas. The best-known meta-metaschema is the Meta-Object Facility (MOF), which is introduced in Sect. 18.1. Many metaschemas can be defined as an instance of the MOF. However, the MOF can also be used as a conceptual model (that is, a metaschema) for a restricted subset of schemas, as we show in Sect. 18.2.

Reification,a well-known equivalent in natural language, nominalization, which basically consists in turning a verb into a noun. Reification is widely used in conceptual modeling; conceptual modelers must therefore have a good grasp of it. In Sect. 6.1, we define reification and explain its logical basis. Reifi
