Abstract

See full text

Embodiments extend the relational model and language of standard SQL, to recognize features of higher level entity-relationship models (ERMs). Annotation language is implemented in the data design language (DDL) to incorporate tables and entities Using DDL, annotations are typed structures of metadata. Annotations may be used for types, entities and elements. In the query language (QL), annotations may be added to the standard QL. A reflection program may use the metadata of the annotation language for reflection on the tables or entities.
