// Prisma is the ORM for server-side (API) access to the database
//
// This file defines the schema for the database.
//  - make sure to run 'prisma generate' after making changes to this file
//  - make sure to run 'prisma db push' to sync the remote database with the schema
//
// Database is optional: when the environment variables are not set, the database is not used at all,
// and the storage of data in Big-AGI is limited to client-side (browser) storage.
//
// The database is used for:
//  - the 'sharing' function, to let users share the chats with each other
