Hamilton is more similar to the Prosto data processing toolkit which also relies on column operations defined via Python functions: https://github.com/asavinov/prosto https://github.com/asavinov/prosto However, Prosto allows for data processing via column operations in many tables (implemented as pandas data frames) by providing a column-oriented equivalents for joins and groupby (hence it has no joins and no groupbys which are known to be quite difficult and require high expertise). Prosto also provides Column-SQL which might be simpler and more natural in many use cases. The whole approach is based on the concept-oriented model of data which makes functions first-class elements of the model as opposed to having only sets in the relational model.
