In subject area: Computer Science A spatial database is a type of database that stores and manages large amounts of data with spatial or geographic information. It allows for the storage, retrieval, and analysis of spatial data, such as the shape and location of features. Unlike traditional ...

Go, Stonebraker, and Williams represent maps using polygons in a simple relational database. Surface data has been represented by the triangle structure. A set of triangles represents a three-dimensional surface, each vertex containing such information as elevation and slope (5,7). The GEOGRAF ...
Spatial DBMS A Spatial DBMS is a database management system that is able to efficiently store, manipulate and query spatial data. Spatial data represent objects in a geometric space, for example points and polygons.Spatial DBMSs typically provide dedicated data types to store spatial data, and ...

You can create a spatial index on a table that is not in your schema. Assume that user B wants to create a spatial index on column GEOMETRY in table T1 under user A's schema. Follow these steps: Connect to the database as a privileged user (for example, as SYSTEM), and execute the...
Aurora PostgreSQL-Compatible offers PostGIS extensions for working with geospatial data that allow you to treat that data as first-class objects in your database. For more information about supported geometric types, see Geometric Types. The Oracle spatial data...
This change is not backwards compatible, as the spatial model is different. Layers created in earlier versions would not be readable in this one. To protect against that we throw exceptions on all SpatialDatabaseService. layer finding methods, if they detect the old format. The exception request...
VLDB(Very Large DataBase)。分区表通过对分区列的判断,把分区列不同的记录,放到同的分区中。分区完全对应用透明。 Oracle的分区表可以包括多个,每个分区都是一个独立段(SEGMENT),可以存放到不同的表空间中。查询时可以通过查询表来访问各个分区中的数据,也可以在查询时直接指定分区的方法来进行查询。 分区...
