Are data models representations?

Leonelli ( 2019) grants that data models can be representations, but denies that data themselves are (in general) representations; hence she takes a slightly different view than we do here, as noted above

For an analysis of the epistemology of theoretical models with an emphasis on how models are constructed, see Boon ( 2020 )

What is basic representation model?

As the analyses in the previous section demonstrate, Basic Representation Model provides a logical framework for a critical interrogation of an information object, and is one of many possible tools for conducting this kind of examination

Data models are abstract, visual representations of data points mapped out in a way that makes it easier to understand the connections and workflows needed at a database level – essentially a blueprint of how to build the most optimized database based on the data set.
