Ξ Project:M36 Relational Algebra Engine

Haskell Programming Language Public Domain Hackage Hackage dependency status Build status Windows Build status

Software can always be made faster, but rarely can it be made more correct.

Introduction

Project:M36 implements a relational algebra engine as inspired by the writings of Chris Date.

Description

Unlike most database management systems (DBMS), Project:M36 is opinionated software which adheres strictly to the mathematics of the relational algebra. The purpose of this adherence is to prove that software which implements mathematically-sound design principles reaps benefits in the form of code clarity, consistency, performance, and future-proofing.

Project:M36 can be used as an in-process or remote DBMS.

Project:M36 is written entirely in the Haskell programming language.
