Updating embedded documents mongodb
Let’s say we have an e-Commerce app and we want to model a product on Mongo DB with atomic operations.We can do something like this: In the above document, we have created a model, embedded document.The atomic operations in database terminology is a chained and sophisticated database operations series.In this series, either all aspects of the series will be affected, or nothing will be altered.We can explain atomic operations in Mongo DB clearly with the use of ACID, a.k.a. We should maintain atomicity in Mongo DB by compiling all the related information in a single document, which will update consistently.We can create such type of consistency via embedded documents.There are various Mongo DB update methods for updating documents in a collection, whether it’s for one document, multiple, or all documents.In Studio 3T, the In-Place Data Editing feature takes care of most updates to a single document.
