· MongoDB provides aggregation operations through aggregation pipelines — a sequential series of data processing operations through which the documents go to obtain the final result. In this tutorial, you'll learn by example how to use the most common features of the aggregation pipelines.
01/01/2017 · The aggregation pipeline is a MongoDB framework that provides for data aggregation via a data processing pipeline. That means documents are sent through a .
Aggregations By Example. The following set of chapters provide examples to solve common data manipulation challenges grouped by different data processing requirements. The best way to use these examples is to try them out yourself as you read each example (see Getting Started for advice on how to execute these examples).
· MongoDB Aggregation. Within MongoDB we have the ability to create a data processing pipeline that will get executed against our data once, we can take advantage of MongoDB's aggregation framework to optimise the above way to do paging.. We will start with a simple aggregation pipeline that will use our filter and match every document and return the results:

· MongoDB's design is made up of collections and pages, rather than tables and rows, as it is in relational database systems. Mongo DB can be used for adhoc queries, indexing, resource balancing, aggregation, and serverside JavaScript processing by companies. MongoDB employs a linear databaselike data structure. For data integrity, the NoSQL ...
· Aggregation Pipelines; MapReduce Functions; Single Purpose Aggregation functions (or operations) Actually the first two are real options of performing it and the third one is just the group of operations already created for some common aggregation processes on a single collection count, distinct etc. similar to SQL functions.
· MongoDB's MapReduce capability provides programmatic query processing flexibility not available in Aggregation Pipeline, but at a cost to performance and coherence. MapReduce is a massively parallel process for manipulating and condensing large volumes of data .
· The Aggregation pipeline is a MongoDB framework that provides for data aggregation via a data processing pipeline. That is documents are sent through a multistep pipeline, filtering, grouping and otherwise transforming the documents at each step. It provides SQL "GROUP BY .." type of constructs for MongoDB that run on the database itself.
