Definition

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.

Historical Background

Traditional database design organizes the data of interest into a database schema, which describes objects and their relationships, as well as their attributes. At the...
