Description: Extends the 'mlr3' package with a backend to transparently
    work with databases such as 'SQLite', 'DuckDB', 'MySQL', 'MariaDB', or
    'PostgreSQL'. The package provides three additional backends:
    'DataBackendDplyr' relies on the abstraction of package 'dbplyr' to
    interact with most DBMS. 'DataBackendDuckDB' operates on 'DuckDB' data
    bases and also on Apache Parquet files. 'DataBackendPolars' operates on
    'Polars' data frames.
