Introduction to ORM
Explore the fundamentals of Object Relational Mappers and how they bridge JavaScript objects and SQL databases. Learn the benefits of using ORMs like unified codebases, enhanced security, and flexibility across different SQL systems. Understand why TypeScript is preferred for ORM usage, improving data type safety in Node.js applications.
We'll cover the following...
Overview of ORMs
An ORM is a programming technique that enables us to write queries and manipulate an SQL database using object-oriented techniques without writing SQL code directly. With ORMs, data is converted between two incompatible type systems. ORMs convert simple objects or JSON files as we see in JavaScript, into SQL queries, data types, and simple values that are compatible with SQL. ORMs also generate the logic to retrieve the data, types, and simple values that are very compatible with SQL.
