OLAP and object data models represent different logical
concepts and structures, and therefore separate database
systems with different query languages were developed
based on these models. We show in this paper that it is
desirable and possible to combine these models to represent
realistic modeling requirements. We define in this paper
an OLAP-Object data model that combines the main
characteristics of OLAP and Object data models in order to
represent their functionalities in a common framework. We
use three different types of object classes: primitive, regular
and composite. In the OLAP-Object data model, primitive
and regular classes which represent object structures
can be used for form composite classes that represent OLAP
structures. We define a query language that uses path structures
to facilitate data navigation and data manipulation.
The proposed language uses the concept of an anchor. An
anchor is an object class (primitive, regular or composite)
that is selected as a starting node from which paths structures
can be formed to express queries. The power of the
proposed query language is illustrated through numerous
examples. The syntax and semantics of the proposed language
are developed.
