doobie
Functional JDBC layer for Scala
doobie is a pure functional JDBC layer for Scala and Cats. It is not an ORM, nor is it a relational algebra; it simply provides a functional way to construct programs (and higher-level libraries) that use JDBC. For common use cases doobie provides a minimal but expressive high-level API. doobie is a Typelevel project. This means we embrace pure, typeful, functional programming, and provide a safe and friendly environment for teaching, learning, and contributing as described in the Scala Code... -

RAQUEL : "Relational Algebra Query, Update and Executive Language"
The project has 2 related sets of aims. As a language, RAQUEL is to : 1. be a pure relational algebra language (unlike SQL) as defined by Date & Darwen's "The Third Manifesto"; 2. incorporate a generalised extension of the ANSI-SPARC 3-layer DB architecture; 3. have the maximum ratio of functionality to conceptual complexity (as defined by Fred Brooks). As a DBMS, RAQUEL is to : 1. have an Open Architecture, enabling a variety of DBMS configurations of 'black box' code, each... -

Relational Algebra for MySQL
A relational algebra interpreter for MySQL databases
A robust Java implementation of relational algebra (RA) interpreter for MySQL databases. The interpreter receives relational algebra queries, converts them to equivalent MySQL queries, executes them, and prints the answers. Compiler tools JFlex and JCup are used to parse RA queries. Rigorous semantic checks are enforced so that invalid queries are not executed. The system is built as a Java terminal application. -

Springbok
Educational Query Tool for Relational Databases
Relational Algebra is a very important formal language associated with relational databases. This is why most of the universities have Relational Algebra as an integral part of their database management courses. But unfortunately, most of the traditional relational DBMS software tools support Structured Query Language (SQL) only. For a student it is very difficult to know whether a relational algebra query written on paper is correct or not. Also as an instructor it is difficult to evaluate... -

Kiel University Relation package
Fast C library for relation algebra using binary decision diagrams.
Kure is a C library which provides manipulation of relations and operations of relation algebra using a fast implementation using binary decision diagram. It provides a Lua based domain-specific embedded programming language to conveniently manipulate and work with relations. For instance, given relations R, S, the tupling of them can be computed using [R,S] and they can be composed using R*S. -

esProc SPL
An intriguing programming language and a data computing middleware
... times. When working as a data warehouse, esProc SPL does not adopt the relational algebra-based SQL syntax. It invents an algebraic system called discrete data set instead: SPL: a database language featuring easy writing and fast running to solve the problems of hard-to-code complex SQL. You are welcome to post your troubles and problems when trying to achieve high performance computing and discuss with us to find a solution.
