Mongoose is a module that connects Node.js to MongoDB in an object document mapper (ODM) style. It offers the Create, Read, Update, and Delete (also known as CRUD) functionalities for documents stored in the database. Mongoose defines the structure of the used documents using schemas. The schema is the smallest unit of data definition in Mongoose. A model is built out of a schema definition. It is a constructor-like function that can be used to create or query documents.
