Esri Geodatabase – How to Differentiate Between Append and Load Data in ArcGIS?

Question

I confused about differences between Append tool in Arctoolbox and Load data in Geodatabase.
I think both of them are the same in the result feature class.Both of them use a default output feature class and compare the target feature geometry and schema with another feature but there are differences in some aspects such as performance that I don't know .Another question is that where can i use Append instead of Load data ?

Thanks for advance

Answer 1

The Object Loader and Simple Data Loader allow you to load data into empty feature classes or feature classes that already contain data.

The Simple Data Loader also allows you to load into stand-alone tables.

While the Object Loader and Simple Data Loader are similar loading wizards, the Object Loader provides the following functionality that the Simple Data Loader does not have:

Because the Object Loader loads data during an edit session in ArcMap, once you've finished loading, you can undo the changes if needed. If the feature coordinates you're loading are not precisely located, you can choose to honor the current snapping environment, snapping coordinates as they load. If you're loading into a feature class that has validation rules, such as attribute domain or geometric network connectivity rules, you can validate the features added and create a selection of the loaded features that are in violation of these rules. With the Object Loader, you can load into feature classes in a geometric network, feature classes in a relationship with messaging, or feature classes that have feature-linked annotation. You cannot load into these types of feature classes with the Simple Data Loader.

Appending Geoodatabases

Append geoprocessing tool. This is useful if loading data is going to be used as part of a batch process, but generally the above methods are better for all other occasions
