Abstract
This paper presents concept of an alternative, semantically richer execution of queries to a relational database. We outline the formal extension of Relational Algebra to form Semantic RA that serves as the formal foundation for construction of new facility called Semantic SQL (SSQL). SSQL is a modification of SQL allowing matching and subsequently elimination of semantic duplicates. This new facility has no impact on targeted database content and existing applications. Queries expressed in SQL are executable as before and SSQL becomes only an optional alternative. A brief description of an implementation of SSQL for SQL Server 2005 concludes the paper.
