Zusammenfassung:Abstract: "Relational algebra in the sense of Schroder and Tarski has been thoroughly studied by mathematicians from the universal algebraic viewpoint and some research has shown many applications of the relational calculus in the fields of graph theory and computer science. This paper addresses the field of process-algebraic languages, which are used for the specification and verification of communicating systems. The construction of a bridge from process algebra to relational algebra is investigated. A process-algebraic language is propounded by adding a parallelism operator to the structure of relational algebra; its semantics is given by the action graph model
The action graph model follows the interpretation of concurrent processes by finite partial orders and, technically, it is constructed by viewing relation algebras as boolean algebras with operators. It establishes a correspondence between relational algebra with parallelism operator and a process algebra, which, in particular, carries an additional combinator playing the role of 'undo'.
