What is Schevo?

Schevo is a pure-Python, SQL-free  object-relational database (ORDBMS).

We focus on making complex database schema not only fun to write, but enjoyable to maintain.

Use Python to store complex data structures, including some benefits of RDBMS, with zero lines of SQL!

Inactive projects

Sometimes we create projects as experiments or specific purposes, and they fall behind in terms of development and support.

Rather than remove them, we call them "inactive" in case someone finds them interesting or useful enough to "reactivate".
