RA (``radb``): A relational algebra interpreter over relational databases

=========================================================================

RA is a simple relational algebra interpreter written in Python 3.  It

is built on top of an SQL-based relational database system.  It

implements relational algebra queries by translating them into SQL and

executing them on the underlying database system through `SQLAlchemy

`_.  RA is packaged with `SQLite

`_, so you can use RA as a standalone

relational-algebra database system.  Alternatively, you can use RA as

a relational-algebra front-end to connect to other database servers

from various vendors.

You can follow the `project `_ on

GitHub, or read its documentation `here
