Conceptual Modeling: Enhancement Through Semiotics

Abstract

Conceptual modeling uses languages to represent the real world. Semiotics, as a general theory of signs and symbols, deals with the study of languages and is comprised of syntax, semantics, and pragmatics. Pragmatics includes the explicit representation of the intentions of users. A common assumption is that all levels of database design (user, conceptual, logical, and physical) can be modeled using the same language. However, languages at the conceptual level are often enhanced by concepts that attempt to capture inherent pragmatics. This research proposes that concepts from semiotics can provide the background needed to understand an application. Specifically, pragmatics and semantics are considered at both the user and conceptual level, based on proposed constraints.
