Postgres is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. ## ORM of choice This section mentions something about Authentication Cascade uses [Prisma](https://www.prisma.io/) as its ORM of choice. Prisma is a modern database toolkit that makes database access easy with an auto-generated and type-safe query builder that's tailored to your database schema. Prisma connects really well to Postgres & NextAuth trough an adapter that makes it easy to use. Whenever you want to make changes to database schema, you can do so by changing the schema in the `schema.prisma` file and then running `npx prisma migrate dev` to generate a migration file and apply the changes to the database. ## Database schema Database has a few main overlapping sections, those are clearly visible in prisma schema(content of each model omitted fro brevity) User related: ``` model Account { ... } model Session { ... } model User { ... } ``` Payments & Subscriptions related: ``` model LemonSqueezySubscription { ... } model OneTimePurchase { ... } model Plan { ... } ``` Feature usage related: ``` model FeatureUsage { ... } ```
