This naming convention helps prevent duplicate field names when the target table and a join table have common field names. In most cases, appended columns are named. Symbology or labeling that is based on an appended column is returned to a default state when the join is removed. When a join table is removed, all data from tables that were joined after it is also removed, but data from previously joined tables remains. Several tables or layers can be joined to a single table or layer, and relationship class joins can be mixed with attribute joins. You will only see join by relationship class listed if you are joining geodatabase data for which a relationship class has already been defined in the geodatabase. You can choose to define the join based on either attributes or a predefined geodatabase relationship class or by location (also referred to as a spatial join). Joining data is typically used to append the fields of one table to those of another through an attribute or field common to both tables.
