SQL or Algernon queries

Abstract

According to initial claim and strategy statements, Semantic Web will play the role of a complement for the current web which is mostly understandable by human users and intends to overcome this limitation and extends the recognition of web information to machines. We have been told that current RDBMS are old and RDF with OWL, SPARQL and Algernon are the new wave replacement, furthermore, RDBMS are useless because the schema must be defined before hand and are difficult to maintain and hard to work with. While Semantic Web implementations are far easier to work with and to maintain. In this paper, the properties of SQL and RDBMS have been discussed and compared opposed to properties of OWL and Algernon, moreover, many queries in the relational-algebra expression form have been judged against Algernon inference queries. In this contention will have been affected readers idea, the preference of databases are exposed and the rules clearly specified that Semantic Web researchers not only must not close the eyes to RDBMS, but also must combine it with new areas of research.
