• Technology oerview
• Database
• Middleware
• Discussion

Maps, Geocoding, Search

Store and query spatial information
SELECT c.holding_company, c.location
FROM competitor c,
bank b
WHERE b.site_id = 1604
AND SDO_WITHIN_DISTANCE(c.location,
b.location,
'distance=2 unit=mile') = 'TRUE'

Store and retrieve geospatial imagery

Store and analyze geospatial networks

Store and manage 3D data

Supports all Geospatial Datatypes
Polygons
(admin, sales territories,
high risk zones)
Locations Networks
(points of interest) (roads, utilities)
Data
3D data type
Imagery
(city models)
(satellite imagery) Topology

Oracle FMW MapViewer
• Map rendering service: Server component
• Provides a comprehensive set of APIs:
• XML, Java, and AJAX-based
• Enables easy development of client viewers
• Enterprise solution for management of map content and
metadata
• Oracle Maps
• A map cache server
• Caches and serves pre-generated map image tiles for base map layers
• A feature of interest (FOI) server
• Renders dynamic geospatial features on top of base map layers
• An Ajax-based JavaScript mapping client library
• Fetches map tiles and FOI from the server
• Controls user interaction with maps and dynamic features.
• Map Builder
• Utility for creating and managing map metadata
• Create, modify, delete: Styles (colors, text, line, markers), Themes, Map
definitions

“Spatial is not special”
• Location is a CORE element of enterprise data
• Location should be openly accessible to the spectrum
of platforms (GIS and non-GIS)
• Location should be a 1st class citizen of enterprise data
management
Try to imagine another core data type being managed
without the benefits of data management ‘best practices’
