ABSTRACT
A family of sequence operations (rs-operations), based on pattern matching and including most of the “natural” operations on sequences, is introduced. In order to apply rs-operations to calculus-like query languages, a logic about sequences (SL) is defined by converting rs-operations to special predicates. To illustrate the applicability of our concepts to database queries, rs-operations and SL are used in an algebra and a calculus, respectively, over an extended relational data model containing sequences.
