  • The Aldat project advocates the algebraic approach to data. This paper reviews this approach in the context of the persistent data type, relation, and the algebraic operators needed when including relations in a programming language. The relations discussed are the classical ones of Codd. The relational algebra consists of two families of binary operators and one of unary operators, and includes Codd’s as a special case. We also review a domain algebra of two categories of operator. To… CONTINUE READING
