Add Features to an Existing ArcSDE Feature Class
Create and Edit Data
Add Attribute Data Based on Constraints
Join Attribute Data to a Geospatial Feature
You can temporarily attach external data to a feature class in your map by specifying a field that the two data sources have in common. For example, you can add assessment data to a parcel layer, using the APN as the common field. You can view and edit the original feature data and the joined attribute data in the Data Table.
