## Description

Sea-ORM is an asynchronous SQL object-relational mapper and database toolkit for mapping relational tables to strongly typed objects. It provides a relational database mapper for performing CRUD operations across MySQL, PostgreSQL, and SQLite, and includes a programmatic dynamic query builder for constructing complex SQL statements.

The project distinguishes itself by providing a GraphQL schema generator that transforms database entities into typed schemas with built-in pagination and filters. It also features a dedicated database migration tool for defining and applying versioned schema changes.

The toolkit covers broad capability areas including relational data modeling and schema management, where it supports the automatic generation of entities from existing database schemas. It further provides advanced query building features such as aggregate value computation, partial model projection, and linked entity fetching, all executed within non-blocking asynchronous runtimes.

The project includes a command-line interface for database entity generation and GraphQL server bootstrapping.
