Prisma is a type-safe database object-relational mapper that uses a declarative schema to map data models to relational and document databases. It provides a unified toolkit for data access, combining a database driver with tools for schema management and record manipulation.
The project features a multi-database driver that standardizes interactions across PostgreSQL, MySQL, and MongoDB. It includes a system for tracking and applying structural schema migrations across different environments and a graphical user interface for browsing and editing database records.
The system ensures data integrity through static type generation and a type-safe client, allowing for query execution with automatic type checking. It translates high-level data modeling into physical database tables or collections via a declarative schema definition.
