Extending the Relational Algebra to Support Transaction Time

Download www.cs.arizona.edu

In this paper we discuss extensions to the conventional relatronal algebra to support transaction time We show that these extensions are applicable to hrstorlcal algebras that support valid time, yleldmg a temporal algebrarc language Smce transaction time concerns the storage of mformatlon m the database, the notion of state IScentral The extensions are formabsed usmg denotatlonal semantics The addltlons preserve the useful properties of the conventional relational algebra
