Object-oriented databases have been introduced primarily to ease the development of database applications. ...
For instance,
a query lan-
guage is a core component
of a view mechanism,
and
a number
of query
languages
have been proposed
for
object-oriented
databases
(e.g., [4, 19, 10] ). ...
Our starting point is a standard object-oriented database model, the Oz model [5, 16] . In this model, the database consists of a hierarchy of classes. ...

A view mechanism can help handle the complex semantics in emerging application areas such as image databases. This paper presents the view mechanism we defuted for the DISIMA image database system. ...
Since DISIMA is being developed on top of an object-oriented database system, we first propose a powerful object-oriented view mechanism based on the separation between types (interface functions) and ...
View mechanisms are useful in other newly emerging application areas of database technology. In this paper, we discuss a view mechanism for one of those areas, image databases. ...

From this point of view a key aspect is represented by the database querying features. ...
Conclusions We consider that this new syntax for SE-LECT and FROM clauses permits to obtain a graph of objects, thus simplifying development of object-oriented software. ...
