Abstract

Even though SQL has become widely accepted as a language for implementing relational database schemas and querying data, there are cases where its users experience the need for new language abstractions which would allow them to express data modeling and querying solutions in a clearer and simpler manner. This paper describes the idea of language extensions to SQL:1999 that come in form of independent packages and may be implemented by different vendors. A translator system uses information imported from the packages to translate the statements containing the extensions into SQL:1999-compliant statements.
