check_key

Check if the specified set of attributes can be the key of the table.

The geographic dimension plays a fundamental role in
multidimensional systems. To define a geographic dimension in a star
schema, we need a table with attributes corresponding to the levels of
the dimension. Additionally, we will also need one or more geographic
layers to represent the data using this dimension. The goal of this
package is to support the definition of geographic dimensions from
layers of geographic information related to each other. It makes it
easy to define relationships between layers and obtain the necessary
data from them.
