Abstract: Granular computing (GrC) is an emerging discipline of information theory that strives to allow reasoning and analysis based on varying levels of information granularity (from fine to coarse). In GrC, the entire information universe can be organised based on many different criteria, allowing the information to be abstracted, aggregated, classified, generalised and so on, based on various characteristics (e.g., data similarity, operational usage, etc.). As a result, GrC relies on information models to describe the universe, the elements of the universe and the composition of each element. In this paper, candidate information models for GrC are explored and assessed, including: the attribute-based data model, the relational data model, the functional data model and the extensible markup language. This includes a description of these models in terms of their concepts, data definition and data manipulation and an analysis of the suitability in support of GrC.
