ABSTRACT
Today, the restricted data type domains of the relational model affect Information Systems design. We claim another approach where the Information System designers would be able to portray directly the real world in a database model that provides more powerful and composite data types, as those of the real world. However, more powerful databases models need the introduction of data query and manipulation languages that reflect the features of the new composite data types. We introduce such a language and also reveal a direct consequence, which is the introduction of higher database design levels.
