TLDR
With the current trends in Object-Oriented Databases (OODB) and a better understanding of relationships of the Object Model with the relational Model, TIGRIS and similar GIS and GIS components will become the norm and eventually replace the current limited systems.About:

Geographical data modeling
TL;DR: This work reviews the alternative data models available in spatial databases, and assess them from the perspective of accurate representation of geographical reality, particularly for three dimensions and time dependence.
Journal ArticleDOI
Making Space for Time: Issues in Space-Time Data Representation
TL;DR: This work gives a historical overview of the development of space-time representation in the geographic information systems and database communities and a review of the most recent research, and questions what seems to be a spirit of self-accusation within the context of this perspective.
Journal ArticleDOI
Object-oriented approaches to geo-referenced information
TL;DR: The author argues that object-oriented approaches can be taken at each of these layers of any computerized system, with a high-level system-independent conceptual model of the application domain supported by increasingly system-oriented models beneath.
Journal ArticleDOI
A conceptual framework for incorporating cognitive principles into geographical database representation
TL;DR: The pyramid framework is described as an example of a new approach to GIS data models that provides the means to create multiple structural interpretations of observed geographic data and the ability to build knowledge hierarchies through the application of data mining and other statistical techniques.

System for dynamic segmentation analysis using conversion of relational data into object-oriented data
TL;DR: In this article, a dynamic segmentation of Geographical Information System (GIS) map data, stored in a relational database, converts linear-feature fixed-length attribute arrays into variable length attribute and location arrays for inclusion into an object-oriented map database which can be scanned for candidate values in the attribute and position arrays meeting certain search criteria.

Extending the database relational model to capture more meaning
TL;DR: In this paper, the relational model is extended to support atomic and molecular semantics, which is a synthesis of many ideas from the published work in semantic modeling plus the introduction of new rules for insertion, update, and deletion.
