Expressing an expectations between different tables from a database may look as such:

```python

from datajudge import BetweenRequirement

companies_between_req = BetweenRequirement.from_tables(

    db_name1="example",

    table_name1="companies",

    db_name2="example",

    table_name2="companies_archive",

)

companies_between_req.add_row_superset_constraint(

    columns1=["name"], columns2=["name"], constant_max_missing_fraction=0

)

```
