Definition

A conceptual model provides a notation and formalism that can be used to construct a high-level, implementation-independent description of selected aspects of the “real world,” termed a miniworld. This process is called conceptual modeling, and the resulting description is referred to as a conceptual schema. Conceptual modeling is an important part of systems analysis and design. A temporal conceptual model provides a notation and formalism with built-in support for capturing temporal aspects of a miniworld during conceptual design.

Historical Background

Temporal applications need to represent data semantics not only related to “what” is important for the application but also related to “when” it is important. The history of temporal conceptual models can be viewed in terms of two generations. The first-generation temporal conceptual models, e.g., [ 2, 14], provide support for only user-defined time; see Fig. 1a for an example. In contrast to the first generation, the second-g...
