Is it possible to join attributes by nearest?
In 2019 this may be possible with the QGIS 3 Zanzibar tool ‘Join attributes by nearest’. This tool allows you to find the closest feature and join selected attributes. It is also possibly to do a one-to-many join, if you specify the max distance and the max nearest neighbors.
How is a table of data related to a layer in ArcGIS?
Typically, you’ll join a table of data to a layer based on the value of a field that can be found in both tables. The name of the field does not have to be the same, but the data type has to be the same; you join numbers to numbers, strings to strings, and so on.

How to join the attributes of features by their location?
These types of queries can be answered with a spatial join. A spatial join joins the attributes of two layers based on the location of the features in the layers. Like joining two tables by matching attribute values in a field, a spatial join appends the attributes of one layer to another.
How is the nearest feature determined in ArcGIS?
Like joining two tables by matching attribute values in a field, a spatial join appends the attributes of one layer to another. The nearest feature is defined as the feature that is geographically closest to another one. Proximity is based on straight-line distance between features.
