-# Type orm
+# TypeORM
+
+TypeORM is an ORM that can run in NodeJS, Browser, Cordova, PhoneGap, Ionic, React Native, NativeScript, Expo, and Electron platforms and can be used with TypeScript and JavaScript (ES5, ES6, ES7, ES8). Its goal is to always support the latest JavaScript features and provide additional features that help you to develop any kind of application that uses databases - from small applications with a few tables to large scale enterprise applications with multiple databases.
+
+TypeORM supports both [Active Record](https://typeorm.io/active-record-data-mapper#what-is-the-active-record-pattern) and [Data Mapper](https://typeorm.io/active-record-data-mapper#what-is-the-data-mapper-pattern) patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.

 # Prisma
 
-Prisma is a next-generation object–relational mapper (ORM) that claims to help developers build faster and make fewer errors. Prisma takes a different approach to ORMs compared to traditional ORMs. It uses a custom Schema Definition Language (SDL) that automatically writes migrations and generates type-safe code.
+Prisma is an ORM that helps app developers build faster and make fewer errors. Combined with its Data Platform developers gain reliability and visibility when working with databases.
