“…The idea of using conceptual spatial and spatiotemporal data models emerged in the 1990s. Most proposals were extensions of either the ER (e.g., Bédard et al 1992;Tryfona and Jensen 1999;Parent et al 2006a), UML (e.g., Price et al 1999;Bédard et al 2004), or objectoriented data models (e.g., David et al 1993). Spatiotemporal data models are the current focus of research and development, both in academia and in industry: They allow the representation of the past and future evolution of geographic objects as well as moving and deforming objects.…”

Multirepresentation generalizes known concepts such as database views and geographic multiscale databases. This chapter describes the handling of multi-representation in the MADS (Modeling Application Data with Spatio-temporal features) data modeling approach. MADS builds on the concept of orthogonality to support multiple modeling dimensions. The structural basis of the MADS model is based on extended entity-relationship (ER) constructs. This is complemented with three other modeling dimensions: space, time, and representation. The latter allows the specification of multiple perceptions of the real world and modeling of the multiple representations of real-world elements that are needed to materialize these perceptions.

Time is an essential dimension to analyse and understand real-world evolution. Although many temporal extensions to spatial models have been proposed, there is still a need to define modelling methods to describe and represent real-world phenomena. This paper presents a set of design patterns modelling spatia-temporal processes expressed in an object-relationship data model. The proposed framework is based on an analysis of spatia-temporal processes and on properties of object-oriented and entity-relationship data models.

“…He also pointed out the little use of proprietary object-oriented systems, except in cases like Milne, Milton & Smith (1993) and David, Raynal, Schorter & Mansart (1993). Research on the extended relational sy,;tem has also faced difficulties.…”
