Joining Data to GIS Features
Concept Procedure
 
 
 

You can add properties from a different data source to GIS features in your map using joins. For example, you can join employment rates stored in a Microsoft Access database file to city features stored in an SDF file, or to counties stored in an Oracle database. Once you join the two data sources, you can use the joined information to style the feature, the same way you use its native information. For example, you can theme the city features based on the employment rates you joined.
