SPATIAL DATA RELATIONSHIPS
The nature of spatial data relationships are important to understand within the context of GIS.

Spatial data can be most simply defined as information that describes the distribution of things upon the surface of the earth.
and Spatial Data Collection with Implications for Cartography. Proceedings CD of the 19thInternational Cartographic Conference, OTTAWA ICA, August 14 to 21, 1999.
Spatial data are often referred to as layers, coverages, or layers. We will use the term layers from this point on, since this is the recognized term used in ArcGIS.
Spatial data are the lifeblood of an emerging and exciting computer mapping technology know as geographic information systems or GIS. The GIS stores and manages the data not as a map but as a series of layers or, as they are sometimes called, themes.

Models for storing and representing spatial data in a GIS system
There are two main models for storing and representing spatial data in a Geographic Information System (GIS): the raster the vector models: ...
Spatial Data Functions
Spatial data refers to information about the location and shape of, and relationships among, geographic features, usually stored as coordinates and topology.
Spatial Data
Spatial data places the features on the map. The coordinates of a point are the most obvious example of this, but it also incorporates projection systems, line and polygon attributes, and other information.

Spatial data: Date that define a location. These are in the form of graphic primitives that are usually either points, lines, polygons or pixels.
Spatial Data: A geographic dataset which is a collection of data that are individually or collectively attached to geographic locations, such as points, lines, or polygons.
Spatial data - "Any information about the location and shape of, and relationships among, geographic features. This includes remotely sensed data as well as map data" (Gittings & Patterson, 1999).

GIS Spatial Data Architecture Patterns
Figure 4-1 provides an overview of the GIS spatial data architecture patterns. GIS spatial data include points, polygons, lines and their associated attributes.
Non-spatial data
Additional non-spatial data can also be stored besides the spatial data represented by the coordinates of a vector geometry or the position of a raster cell. In vector data, the additional data are attributes of the object.
Spatial data are represented in GISs in two very different ways. Figure 2 shows the two different ways that a stream could be represented in a GIS. Spatial data can be represented as either rasters or vectors.
Spatial data may be located in a variety of different data formats, schemas, and disparate systems.
Spatial Database Catalogs and Libraries are implemented through use of a consistent index and search strategy based on the Hyper-Text Transfer Protocol (HTTP) and Z39.50 Search and Retrieve protocols.
