#+TITLE: Domino * About Domino is a **Relational Algebra Engine** implements relational algebra in its strict, theoretical form, adhering rigorously to the principles of relational theory as articulated by E. F. Codd. A relation is modeled as a set of tuples, each tuple being a set of attributes. Each attribute is a pairing of a name with a value drawn from a domain. All operations are defined on entire relations as sets, with no recourse to the compromises typical of SQL or other practical implementations. The engine is intended as a study in correctness: each operation, from projection to join, is executed in a manner consistent with the classical definition of relational algebra. It is a platform for exploring the consequences of relational theory in a low-level programming context, providing both a tool for experimentation and a concrete realization of the abstract model.
