Remarks

The DataExtraction coclass extracts data from one geodatabase to another geodatabase. It allows you to apply filters such that only a portion of the geodatabase is copied. The geodatabases involved can be either personal geodatabases or ArcSDE geodatabases.

A data extraction is very similar to a check out only in the data extraction case, you can�t edit and check the changes back in.
