A Query Language for EER Schemas

A Query Language for EER Schemas

Download lawley.id.au

We present a proposed query language for extended entity relationship schemas. The language improves on previous proposals by using only concepts explicitly in a given schema. It includes quantifiers and aggregates to allow complex queries to be expressed, and it allows derived subtypes, attributes and relationships to be defined and used in queries. Further extensions are discussed.
