Developing an Oracle-Based Spatio-Temporal Information Management System
نویسندگان
چکیده
In this paper, we present an extension of Oracle, named STOC (SpatioTemporal Object Cartridge), to support spatio-temporal data management in a practical way. The extension is developed as a PL/SQL package and can be integrated into Oracle to offer spatio-temporal data types as well as spatio-temporal operations for various applications. Users are allowed to use standard SQL to access spatio-temporal data and functions. After an overview of the general features of STOC, we discuss the architecture and implementation of STOC. And finally, a case study of STOC is presented, which shows that STOC is effective to represent and query spatio-temporal data on the basis of Oracle.

Spatio-temporal agent based simulation of COVID-19 disease and investigating the effect of vaccination (case study: Urmia)
Proper management of epidemic diseases such as Covid-19 is very important because of its effects on the economy, culture and society of nations. By applying various control strategies such as closing schools, restricting night traffic and mass vaccination program, the spread of this disease has been somewhat controlled but not completely stopped. The main goal of this research is to provide a f...

In this article, growable deep modular neural networks for continuous speech recognition are introduced. These networks can be grown to implement the spatio-temporal information of the frame sequences at their input layer as well as their labels at the output layer at the same time. The trained neural network with such double spatio-temporal association structure can learn the phonetic sequence...

متن کاملA Spatio-temporal Database System Based on TimeDB and Oracle Spatial
The importance of the spatial component of data items has been long recognized and gave rise to a successful line of research and development in Geographic Information Systems (GIS). In many application domains it is also essential to deal with the evolution of data along time and to integrate spatial, temporal and other aspects of the information domain in an expressive and operationally effec...
متن کاملWorking with Spatio-temporal Data Type
Several aspects of spatiotemporal databases have been explored in past decades, ranging from basic data structure to query processing and indexing. But today, operational temporal GIS does not exist. The key impediments have been the complexity of integrating space and time and the lack of standards. OpenGIS standards for simple feature access (spatial type) do exist, but unlike the spatial typ...
