MongoDB CRUD Operations Overview:
CRUD stands for Create, Read, Update, and Delete, which are the four basic operations for managing data in a database. In MongoDB, these operations are performed on documents within collections using specific methods. The Create operation uses methods like insertOne() or insertMany() to add new documents. The Read operation uses find() or findOne() to retrieve documents based on query conditions, and it supports filtering, projection, and sorting to control what data is returned and how it’s presented.

Update and Delete Operations in MongoDB:
The Update operation allows modifying existing documents using methods like updateOne(), updateMany(), and replaceOne(), often combined with update operators such as $set, $inc, or $unset. Updates can target specific fields or replace entire documents. The Delete operation removes documents from a collection using deleteOne() or deleteMany(). MongoDB’s flexible query language allows these operations to be highly targeted or broad, depending on the need, and all CRUD operations can be combined with indexing and filtering for optimized performance.
