What is versioning in GIS?
In most workflow strategies, it is the published version of the geodatabase, representing the current state of the system being modeled. You maintain and update the Default version over time by posting changes to it from other versions. You can also edit the Default version directly, just like any other version.
What is branch versioning ESRI?
Branch versioning is a new platform for multiuser editing that leverages a services-based architecture instead of depending on a database connection. It builds on the well-established capabilities of traditional versioning while improving workflow management.

What happens during geodatabase compression in ArcGIS?
You can use the ArcGIS for Desktop Compress command or the Compress geoprocessing tool or Python script. What happens during compression? Compression first scans into memory the instance’s state tree configuration. Using this information, compression deletes all states that do not participate within a version’s lineage.
How is a candidate lineage compressed in ArcGIS?
The next step collapses any candidate lineage of states into one state. A candidate lineage is a collection of states that can be compressed into one state without affecting the logical representation for any table in a given version. The final step, when applicable, moves rows from the delta tables into the base (or business) tables.
What happens when I compress database to state 0?
If the intention is to compress the entire instance to state 0, then additional steps must first be performed prior to executing the compress command. If the instance has not been compressed to state 0 and there is an attempt to unregister a class as versioned, a warning message may be encountered.
What is the objective of the compress command?
The objective of a compress is to delete non-referenced states, combine states that share the same lineage, and move rows from the delta tables into the base tables. If the compress command does not return an error, the compress is successful.
