A Temporal Algebra with Recursive Equations

  title={A Temporal Algebra with Recursive Equations},
  author={Aky{\"u}z Mehmet and Orgun},
This paper introduces a recursive temporal algebra for querying time-varying data. The algebra, called < , is based on a temporal relational data model in which a temporal database is modeled as a collection of time-varying relations. Each time-varying relation is a collection of ordinary relations indexed by moments in time. In < , recursive queries (such as the transitive closure of a given relation) can be formulated through equations. It is shown that other forms of recursion, such as… CONTINUE READING
