Understanding Prisma

In today's lecture, Harkirat provides an insightful overview of Prisma, discussing the role of Object-Relational Mapping (ORM) systems and how Prisma serves as a powerful ORM for modern application development.

The session later explores the use of Prisma with various databases, the functionality of the Prisma Client, and culminated in a hands-on demonstration of creating a first application using Prisma showcasing its ease of use and versatility in managing database operations.

ORMs

Object-Relational Mapping (ORM) is a crucial concept in modern software development, particularly when dealing with databases in object-oriented programming languages. Prisma is an ORM that exemplifies the use of this technique. Here's an elaboration on ORMs, with a focus on how Prisma fits into this context:

What are ORMs?

Official Definition

• ORM: Object-Relational Mapping is a programming technique for converting data between incompatible systems using object-oriented programming languages. It creates a "virtual object database" that developers can interact with using their programming language instead of direct database queries.
• Abstraction: ORMs abstract the complexities of the database, allowing developers to work with database records as if they were objects in their code. This includes handling CRUD operations (Create, Read, Update, Delete) and managing database connections and transactions.

Simplified Definition

• Ease of Use: ORMs simplify database interactions by letting developers use the syntax and paradigms of their programming language rather than writing SQL queries. This can make code more readable and maintainable.

Prisma as an ORM

Prisma is a next-generation ORM that takes the concept of ORMs further by providing additional tools and features that enhance the developer experience:

• Schema Definition: Prisma uses a declarative Prisma schema to define the application's data model. This schema is used to generate a Prisma Client that provides type-safe database access.
