Every Column has a Type which defines what sort of data it can contain; additionally the geometry Column (SpatialColumnName) in a spatially enabled Table also has a GeometryType and a CoordinateSystem.

You can find out which indexes a Column participates in using the Indexes property or create a new single-column index using the CreateIndex method.

You can find out whether a Column uses a Domain with the HasDomain property or return the actual domain using the GetDomain method. Where a Table has been subtyped (IsSubtyped is True), each column may have multiple domains defined, one for each subtype value. These Domain objects can also be accessed using the GetDomain method by specifying the subtype index or name of interest.
