Abstract: | Data are organized/stored in a plethora of different databases, locations and data models. In many cases, companies and organizations utilize data stored in a variety of data models at remote database servers. A challenge would be to construct queries that join data from such disparate sources. In this paper, we report on research work relating to graphical query languages and data modeling. More specifically, we report on a new software tool for the novice user, one that transforms databases of different data models (Relational, Object-Relational, Object-Oriented) into an equivalent XML model, plus on a new graphical XQuery type query language that facilitates the construction of user queries that join data from different data models. |
