Discover how to easily read, write, and update data in Oracle. Via demos we'll share how FME lets you transform spatial and non-spatial data for use in Oracle and also provide an easy way to share that data with others -- all of this possible via customizable processes which can be automated. You'll also see how the FME Data Inspector's new Table View mode lets you more easily examine your data in Oracle.
This webinar is the third in our series of database webinars on SQL Server, PostGIS 2.0, and Oracle.

FME also does data of all kinds – doesn’t have to be spatial.
2013 highlights – you can talk about interesting new formats here: INGRES Spatial & non-Saptial Autodesk IMX Odata – web XML/JSON messages Socrata – web based for local Gov. PostGIS Raster & PostGIS 2 Point Cloud: Riegl LaserScan & Terrasolid Terrascan About 30 new formats for 2013
Novice Intermediate Expert I have never used FME (note: next slide will tell them where to get more info)
Not covering the basics of FME, but here is where you can get more background.

Here ’ s what we ’ re using FME 2012 – released yesterday
Multiple choice -Data validation -Geometry validation -Reading data from databases -Writing to databases
Zip reading writing capabilities
Oracle is very forgiving about the kind of spatial data which can be written into the database. Consequently it is easy to get features with invalid geometries into the feature classes. FME offers some transformers which can help with this. Here we have a shape file with all the countries in the world in it. Right away we can guess that we might have problems with Russia, Antartica and perhaps some of those countries which are made up of multiple small polygons. So this example adds this shape data into two tables – one with the geometry spatial type and one with the geography spatial type. Notice that the geography spatial type cannot handle Antarctica because this data appears to have some coordinates with enough precision to drop them below the -90 latitude which is impossible. So it is rejected. A clipper would get around this problem. We assume that because the data has been written that SQL Server will be happy with it but this isn ’ t always the case. Issuing the command Very often spatial data contains invalid geometries. Very important to run validate_geometry_with_context and validate_layer_with_context Import to ensure you have valid geometries – when working with an spatial analysis you want do with your data.
Update: - Extend ArcGIS - ArcMap - open Catalog and add connection to city parks - ArcMap - drag connection into map to open - Properties - categorize by park name - rt-click - Data - Export Data - output feature class - create new geodatabase - save data and add as layer. - remove connection - Editor - start editing - pick park, then choose attributes - change alternate name - choose another park - move vertex - Editor - stop editing and save edits - open 5_DB_Operation and add parks gdb - explain process run workspace, then add updated table to view
There are still a few cities left on the World Tour – if you can spring for a trip to Australia and NewZealand or maybe England or Europe there is still time to find out all the new goodies in FME 2013
