Step-by-step explanation:

The real power of the aggregation framework comes from the aggregation pipeline, which has its roots in the SQL GROUP BY clause.

The aggregation framework in MongoDB allows you to perform complex queries and analyses on your data by utilizing a pipeline of stages to transform and aggregate documents. Each stage in the pipeline processes the input document and passes the transformed output to the next stage.

For example, you can use the $group stage in the aggregation pipeline to group documents by a specific field and perform calculations, similar to how the GROUP BY clause works in SQL. This allows you to compute statistics, generate reports, and gain insights from your data.
