The document discusses the principles of data management in GIS, focusing on how tables can be joined or related based on shared fields. It explains different relationship types, such as one-to-one, one-to-many, and many-to-many, emphasizing the importance of consistent data types over matching column names. Additionally, the order of data within columns or rows is deemed unimportant for these operations.

with a join. Instead, you can access the related data when you work with
the layer's attributes.
