Abstract. This paper presents a methodology for conceptual modeling which is based on a new modeling primitive, the niche, and associated constructs granularity and reconciliation. A niche is an environment where entities interact for a specific purpose, playing specific roles, and according to the norms and constraints of that environment. Granularity refers to the relative level of power or influence of an entity within a niche. Reconciliation is a relationship from N entities onto one reconciled entity, and represents explicitly a situation where two or more different perspectives of the same entity have been reconciled, by negotiation, into a single consensus view. The methodology we propose provides a systematic method of designing conceptual models along with a process for normalising inappropriate relationships. Normalising is a prescriptive process for identifying and remedying inconsistencies within a model based on granularities. Drawing on a number of case studies, we show how niches and granularity make complexity easier to manage, highlight inaccuracies in a model, identify opportunities for achieving project goals, and reduce semantic heterogeneity.

Abstract. An ecological niche is defined by an array of biotic and abiotic requirements that allow organisms to survive and reproduce in a geographic area. Environmental data from a region can be used to predict the potential distribution of a species in a different region. Potential geographic distributions are useful in predicting the extent of invasive species, preventing economic and ecological damages. Many formalisms for modeling geospatial information have been developed over the years. The most notable benefit of these formalisms is their focus on a high-level abstraction of reality, leaving unnecessary details behind. This paper presents the stages of the Model-Driven Architecture approach for the design of database, with geospatial capabilities, for niches and potential geographic distributions. We take advantage of the UML GeoProfile formalism for geospatial databases, which is capable of modeling geographic and environmental data.
