Existing DBMS's are not well equipped to handle continuously changing data. This paper presents behavioral aspect of the spatio-temporal databases for managing and querying moving objects.Our objective is to evaluate and develop a framework for managing and querying moving object database. The ...
However, it is not preferable for implementing new data types and operations in large databases when high performance is required. We have earlier proposed the tight-coupling architecture (Whang et al. 2002 , 2005 ) to satisfy this requirement. In tight-coupling , new data types and operations...
Databases offer several advantages to GISs. They minimize redundancy in data, maintain consistency through sharing of related data and by enforcing a schema for data, ensure the integrity of data, include security constraints for data access and writing, and ultimately reduce costs. DBMS combines a...
Logical models organize data from the perspective of computer systems and are mainly used during the DBMS implementation stage. Hierarchical models and network models are widely employed logical models in the first-generation databases. Hierarchical models are based on tree structure, and network models...

GIS users deal with large, complex data. However, many GIS users still rely on shapefiles or other antiquated forms of vector data. Even ESRI’s “new” file geodatabase lacks the functionality you get from a true DBMS. Creating your own database server can be a daunting task. Even if...
In this section, we discuss two settings that are needed to make sure the spatial columns are migrated successfully to the target: For migrating Oracle databases version 12.1 or earlier to PostgreSQL using AWS DMS, a function is required to convert the Or...
Synonyms Probability threshold indexing;Spatial data indexing with uncertainty Definition TheProbabilistic Threshold Indexing(PTI) method enables efficient query evaluation of a vast amount of spatial data that are inherently uncertain. Spatial data uncertainty is common in Location-Based Services (LBS), whe...
* Examines the strengths of various query languages and approaches to query processing.* Explains the use of computational geometry in spatial databases GISs, providing necessary background and an in-depth look at key algorithms.* Covers spatial access methods, including the R-tree and several spa...
