One of the main problems you have to face on designing a MongoDB schema is how to model "One-to-N" (one to many) relationships. At this point, you may be familiar with the design of MongoDB databases and collections, however what are the frequent patterns you may have to model? Our applications start with an original schema which eventually needs to be altered. So that, operations/queries over designed schemas have so bad performance and/or don't scale. It may come as a surprise to some people, but the biggest impact to performance is how well a data model for a specific application fits with its needs (application patterns). But what if there are outliers in our data? We hope this series will establish a common methodology and vocabulary you can use when •.
