What happens when you combine features from different layers?

What happens when you combine features from different layers?

Union combines selected features into one new feature. Although the features may be from different layers, the layers must be of the same geometry type—either line or polygon. Union maintains the original features and their attributes—that is, the selected features are not deleted or edited during the Union operation.

When to check all features in a join layer?

When checked, all features in the target layer are returned in the output, even if the target feature does not have a match in the join layer (a left outer join). An example of one-to-one and one-to-many attribute joins, with and without Keep all target features checked.

Can you count the number of features in a summarize?

How is the passing of data between layers?

We will be analyzing the passing of data between layers from two perspectives: how the data will come towards the data access layer, and how the data will pass to UI. As you read the article you would understand better why I want two perspectives.
