Other approaches allow avoiding the use of such names at least in some cases. An approach of this other kind is, for instance, the one of Tent and Zi...

In this paper we introduce the representative object, which uncovers the inherent schema(s) in semistructured, hierarchical data sources and provides a concise description of the structure of the data. Semistructured data, unlike data stored in typical relational or object-oriented databases, does not have fixed schema that is known in advance and stored separately from the data. With the rapid...

In this work, a method for generating external schemas in object oriented databases in the ODMG framework is proposed. External schema generation involves obtaining all the relationships existing between the classes selected to make up an external schema. This generation process is part of an external schema definition system that we are developing, which allows the definition of external schem...

Given that ODMG 3.0 specifications do not address the definition of external schemas, we are developing an external schema definition methodology for ODMG databases. In this paper, an extension of ODMG metadata is proposed to support the definition of external schemas. In particular, metadata for derived classes and derived interfaces are defined, as well as some modifications to define inherit...
