 # Aggregation pipeline and commands
 
 Aggregation operations involve performing various operations on a large number of data records, such as data grouping, sorting, restructuring, or modifying.
 These operations pass through one or more stages, which make up a pipeline.

 Each stage acts upon the returned documents of the previous stage, starting with the input documents.
 As shown above, the documents pass through the pipeline with the result of the previous stage acting as input for the next stage, going from `$match` => `$group` => `$sort` stage.
