This paper proposes a number of type-system and language

extensions to natively support relational and hierarchical data within a

statically typed object-oriented setting. In our approach SQL tables and

XML documents become first class citizens that benefit from the full

range of features available in a modern programming language like C]

or Java. This allows objects, tables and documents to be constructed,

loaded, passed, transformed, updated, and queried in a unified and typesafe

manner.
