ArcPy are just python wrappers on top of ArcObjects, so the same concepts apply, except that you have less explicit control of triggering the right behaviors.

comment What is the hierarchy of features in ArcGIS? Is it different in other software?
Expansing on my comment above, I guess I also would like to emphasize that there is not such a thing as a "GeoDatabase storage format." Nevertheless Personal GDB, FileGDB are file-based GDB-compliant storage formats. Even ppl at ESRI make the mistake of not doing the distinction all the time.

The increase in memory usage hints that you might be using the wrong cursor, or are leaking geometries. Can you post a sample of what you are doing?

I wont try to explain all of it since everyone is jumping on this. What I will tell you is that a Shapefile is a storage format for spatial data that conforms to the OGC Simple Features Specification. Contrary to popular belief, The GeoDatabase is not a spatial format... it is an information model that specifies how various spatially-enabled object-relational entities interact with each other (FeatureClasses, network datasets, topologies,etc). There are various implementations of that model (Personal GDB, FileGDB, Enterprise (ArcSDE) GDB. The rest, I will leave for others :)

@Craig the UI creates a template of a Null geometry, but it will not allow you to save it. If you find a way to do it through thr UI, it is a bug.

comment How to migrate data from ArcSDE to PostGIS?
One of reasons I wrote the ArcObjects GDAL driver was to do exactly this. Since they have an ESRI license, the wanted to maintain their complex FeatureClasses and dump them to PostGIS every night. The arcsde driver goes through the arcsde api layer, but the arcobjects driver goes, well, through arcobjects. We have been using it for a year and it has worked quite nicely.

comment Why has Web Mercator (auxiliary sphere) become the web map standard?
@mkennedy I guess I am biased, too. I spent too many hours of my life debugging code that had missing spatial reference information, trying to match proj strings and/or trying to do other projection matching voodoo because of this very "Google projection" situation. I guess that makes me cranky, too :)
