Spatial Data Models in Current Commercial Rdbms
نویسنده
چکیده
Vendors of database software are adding spatial capabilities to their products. This paper compares the spatial data types and the spatial relations which are recognized by a set of current commercial RDBMS and layered spatial database management packages. While there is convergence on the notion that databases should handle spatial information, there are both gross and subtle differences in what this means. A range of types, relations, capability, and ease of use is evident.

Development of SISGeM - An Online System for 3D Geologic Modeling -
GIS can be readily used to manage and analyze 2D information and also afford 3D visualization of surface features. However, general-purpose GIS packages do not offer capabilities for constructing or visualizing 3D geologic models. GIS tools must, therefore, be appropriately tailored to handle geologic data and accommodate the special spatial analysis needs of geologic information. Since 3D geol...
متن کاملEfficient Temporal Coalescing Query Support in Relational Database Systems
The interest in and user demand for temporal databases have only increased with time; unfortunately, DBMS vendors and standard groups have not moved aggressively to extend their systems with support for transaction-time or valid-time. This can be partially attributed to the expected major R&D costs to add temporal support to RDBMS by directly extending the database engine. The newly introduced ...

متن کاملDB2 Spatial Extender - Spatial data within the RDBMS
Much of the data that we encounter has a spatial (geographic locational) aspect yet this has not been readily exploited by traditional RDBMS. Over the past five years there has been a confluence of Geographic Information System (GIS) technology, RDBMS architecture and SQL standards that has fostered the implementation of spatial processing within the RDBMS. This paper will present a brief overv...
متن کاملTransaction reordering
Traditional workload management methods mainly focus on the current system status while information about the interaction between queued and running transactions is largely ignored. This paper proposes using transaction reordering, a workload management method that considers both the current system status and information about the interaction between queued and running transactions, to improve ...
