MongoDB Aggregation

MongoDB's aggregation framework allows developers to process and transform data through a pipeline of stages, similar to a data processing workflow.

Aggregation Pipeline

A pipeline consists of stages like filtering, grouping, and sorting, each passing its output to the next stage to produce a final result.

Common Stages

Stages such as match, group, project, and sort are commonly combined to summarize data, calculate totals, or reshape documents.

Use Cases

Aggregation is often used for reporting, analytics, and generating summarized views of data directly within the database.
