Structured documents (e.g., SGML) can benefit a lot from database support and more specifically from objectoriented database (OODB) management systems. This paper describes anaturai mapping from SGML documents into 00DB's and a formal extension of two 00DB query languages (one SQL-like and the other calculus) in order to deal with SGML document retrieval. Although motivated by structured documents, theextensions of query languages that we present are generai and useful for a variety of other

The new features allow to query data (and to some extent schema) without exact knowledge of the schema in a simple and homogeneous fashion. 1The inverse mapping from database schema/instances to SGML DTD/docurnents also opens interesting perspectives for exchanging information between heterogeneous databases, writing reports, etc. This is not considered in the present paper.
