Spatio-Temporal Database and Its Models: A Review

Literature review of spatio-temporal database models

Recent efforts in spatial and temporal data models and database systems attempt to achieve an appropriate kind of interaction between the two areas. This paper reviews the different types of spatio-temporal data models that have been proposed in the literature as well as new theories and concepts that have emerged. It provides an overview of previous achievements within the domain and criticall...

Spatio-temporal Database Management Systems

This chapter is devoted to architectural and implementation aspects of spatiotemporal database management systems. It starts with a general introduction into architectures and commercial approaches to extending databases by spatiotemporal features. Thereafter, the prototype systems Concert, Secondo, Dedale, Tiger, and GeoToolKit are presented. As we will see, the focus of these systems is on di...

A Theory of Spatio - Temporal Database

A Theory of Spatio-Temporal Database Queries

We address a fundamental question concerning spatio-temporal database systems: “What are exactly spatio-temporal queries?” We define spatio-temporal queries to be computable mappings that are also generic, meaning that the result of a query may only depend to a limited extent on the actual internal representation of the spatio-temporal data. Genericity is defined as invariance under transformat...

Science Communication, A review on Importance, History, and Its Models

The article is an extended version of a talk on the issue given in Half-Day Seminar on the Complications of Scientific Publications held by Iranian Academy of Sciences, on July the ninth of 2019. Apparently, science communication, an old tradition and once very popular according to the literature reviewed, is not well advanced along with the magnificent scientific progress happened during the l...
