ORMs and Node.js: Layers of abstraction.

I’ve also deployed applications using ORMs and regret nothing. They are used by production applications all around the world which merrily respond to plenty of requests every day. A lot of hard work has gone into each and every one of them. I don’t intend to diss any of the modules mentioned in this post. While the concepts discussed are applicable to every language and platform, the code examples will be written in Node.js-flavored JavaScript, and we will be considering packages obtained from the npm repository. However, in this tutorial, we’ll consider three reasons why you should avoid using ORM in your project. Thus, ORM improves readability, documentation, and the speed of development. Consequently, it also provides a layer of abstraction over the SQL statement by allowing developers to operate on the object instead of going through the hassle of writing SQL queries. The result of this is that ORM creates a structure for CRUD operations in our database. And this means we map relational sequel objects - foreign keys and primary keys to actual objects. In a nutshell, ORM refers to object-relational mapping. The article was also updated to remove outdated information and make general edits.
