Understanding ORM/ODM libraries
ORM and ODM are programming techniques that provide a higher-level abstraction for database interactions. They allows you to interact with databases using object-oriented programming concepts, making database operations more automatic and less dependent on raw SQL queries.
- ORM (Object-Relational Mapping): Primarily used with relational databases, ORM translates between objects in code and rows in a relational database table.
- ODM (Object-Document Mapping): Built for NoSQL databases like MongoDB, ODM maps between objects in code and documents in a NoSQL database collection.
What is the use of ORM/ODM libraries like Mongoose in Express applications ?
If you build web applications with Node and Express, you know how quick and easy it is to get a server up and running. Routing, middlewares, template rendering – Express has you covered on the core web dev stuff. But every application needs to work with data at some point. Saving user records, storing file uploads, retrieving info for display that’s when developing the application becomes harder..
Interacting with MongoDB directly means wrangling connections, writing tedious CRUD operations, and translating results. That’s why smart Express developers reach for Mongoose – the leading Object Document Mapper (ODM) for MongoDB in Node. Mongoose makes modeling and working with data worlds simpler, so you spend less time-fighting databases and more time building great apps.
