How to fill out mongodb aggregation and data?

1. Start by understanding the basic concept of mongodb aggregation. Aggregation in mongodb is the process of retrieving, transforming, and combining data from multiple documents of a collection into a single result.
2. Familiarize yourself with the aggregation pipeline. The aggregation pipeline is a framework within mongodb that allows you to process and transform data using multiple stages. Each stage performs a specific operation on the input data and passes the result to the next stage.
3. Begin by defining the stages of the aggregation pipeline. The stages can include operations such as $match, $group, $project, $sort, $limit, $skip, $lookup, and many more. Each stage helps filter, manipulate, or reshape the data according to your requirements.
4. Use the $match stage to filter the documents in the collection based on specific conditions. This stage allows you to specify conditions using query operators to find relevant data.
5. Utilize the $group stage to group the documents based on specified fields. This stage allows you to perform operations like counting, summing, averaging, and more on grouped data.
6. Employ the $project stage to shape the output documents by including or excluding fields, calculating new values, renaming fields, or performing other operations on the data.
7. Use the $sort stage to sort the documents based on specified fields or values. This stage allows you to specify the order in which the result should be presented.
8. Apply the $limit stage to restrict the number of documents in the output. This stage is useful when you want to retrieve only a specific number of results.
9. Consider using the $skip stage to skip a specified number of documents in the aggregation. This stage is useful when you want to skip a certain number of results and retrieve the rest.
