Versioned Editing • Workflow that manages concurrent multiuser editors on a single ArcSDE data source • Versions represent states or views of the geodatabase • Edits are maintained in delta tables until compression
Comparing Past and Present • Before: • Have single editor in each file geodatabase • Notify editors when to disconnect from database • Copy edits from the file geodatabases to a staging file geodatabase, then push those to SDE • Repeat process for each database • After: • Multiple editors in same source • Run maintenance when all users disconnected
Benefits of Versioned Editing • Eliminating dataset duplicates • Faster processing times for dataset edits • Version control • Collaboration
The To-Do List • Register data as versioned • Create versions and grant privileges • Provide training to editors

Tips • Reconcile edits before beginning an edit session • Database administration • Everyone has to be out of database in order to perform full compression • Checking the process_information table was cumbersome (fixed in 10.1) • Need elevated permissions to disconnect users
Troubleshooting • Resolving conflicts • Do not reach full compression • Locks on the database • Deleting tables from the back end • Transaction logs become full
The Road Ahead • Implement versioned editing to more SDE databases • Need a more automated QA process • Work on automating maintenance scripts as scheduled tasks
Tools • Administration tools in ArcGIS • Python scripts • ArcGIS Diagrammer • GDBT for 10.0/10.1 • Troubleshoot, monitor, and investigate databases • Show Edits Since Reconcile Tool • Generates feature class of all edits between versions • Edit tracking tool
