Explanation/Reference:
The linear referencing system (LRS) application programming interface (API) in Oracle Spatial provides server-side LRS capabilities at the cartographic level. The linear measure information is directly integrated into the Oracle Spatial geometry structure.
Geometric segments are basic LRS elements in Oracle Spatial. A geometric segment can be any of the following:
Line string: an ordered, nonbranching, and continuous geometry (for example, a simple road)

Multiline string: nonconnected line strings (for example, a highway with a gap caused by a lake or a

bypass road)
Polygon (for example, a racetrack or a scenic tour route that starts and ends at the same point)

Incorrect Answers:
A: Effective with Oracle9i, Spatial provides a rational and complete treatment of geodetic coordinates.
Effective with release 9.2, ellipsoidal surface computations consider the curvatures of the Earth in the specified geodetic coordinate system and return correct, accurate results. In other words, Spatial queries return the right answers all the time.
B: For a polygon with holes, the outer boundary must be stored first in the SDO_ORDINATES definition, followed by coordinates of the inner boundaries.
C: A Polyline object is a shape defined by one or more paths, in which a path is a series of connected segments.
D: Oracle Spatial supports the creation and storage of three-dimensional geometry objects, Effective with Oracle Database Release 11.1, Oracle Spatial supports the storage and retrieval of three- dimensional spatial data, which can include points, point clouds (collections of points), lines, polygons, surfaces, and solids.
