Aggregation's operations process data records and return computed results

9. Aggregation's operations process data records and return computed results.

1. True
2. False

Answer: A) True

Explanation:

Aggregation operations process data records and return computed results in a single operation. Aggregation operations combine values from multiple documents into a single result, and they can perform a variety of operations on the grouped data in order to return a single result. Aggregation operations can be used to group values from multiple documents together. To aggregate data in MongoDB, there are three methods to choose from. These are the aggregation pipeline, the map-reduce function, and single-purpose aggregation methods.
