Logical aggregates
The last set of special aggregate functions you will use are the logical operators LOGICAL_AND and LOGICAL_OR. These provide an efficient way to find if any data set contains a true boolean. This helps when grouping by data to quickly see if all or one of those values is true. For example, this exercise will look at groups of data to see if they have been delivered or if at least one of the values has been delivered.
