ArcGIS Pro Spatial Join or Relate?

Video #105 In this video I: Use a Spatial Join to add a column from a polygon layer (postcodes) to a point layer (pubs) I then use Add Relate to show the difference between JOIN and RELATE Finally, I create a Relationship Class, stored in the file geodatabase. Key points to remember are: 1. A JOIN uses a common field to associate records from one table to another. Its more aimed at a 1-to-1 relationship. A Spatial Join always creates an output feature class 2. Relates define the actual relationship between 2 tables. No data is appended and you select a record to access the related data. Its basically a sort of 'live link'. Good way to represent a 1-to-Many relationship.
