    It is sufficient to load a table ! All database engines have such a tool to
    load a table in a batch (or to use a delimited tabular text file directly),
    but they all need you provide a formal description of its format using some
    engine-specific syntax (or command line).

    Creating a relational database supposes that you create multiple tables, and
    each one will need to be loaded.

    Unicode does not provide a SQL script to create the database schema, because
    it would be engine-specific (mostly because of datatypes, but also because
    od the syntax for relations, referencial constraints, and unique keys); and
    the data-load SQL commands or tools are also engine-specific. All fields are
    documented however to allow you creating such database the way you want.
