What is aggregation?
- MongoDB Aggregation is a database process that allows us to perform complex data transformations and computations on collections of documents or rows.
- It enables us to group, filter, and manipulate data to produce summarized results. MongoDB Aggregation is typically carried out using the aggregation pipeline, which is a framework for data aggregation modeled on the concept of data processing pipelines.
- Each stage of the pipeline transforms the documents as they pass through it and allowing for operations like filtering, grouping, sorting, reshaping and performing calculations on the data.
