Programming languages, database systems and artificial intelligence systems all have the notion that entities can be classified into types. As might be expected, however, the usage of the notion of type is not the same throughout or even within these areas. In this paper, I propose a notion of typing that is derived from work on programming languages and indicate how this notion might be used in the context of database systems. Thus, the paper is a step toward unifying the notions of type in data-bases and programming languages.
