Abstract :
For the past few decades, there has been a significant interest in data integration, and lots of work has been introduced in this
field. Herein we discussed a way to handle the problem of integrating heterogeneous data model, namely relational and XML.
Since the relational model is the most data model used to manage data for years. Similarly, XML is rapidly becoming more and
more popular as a standard format for exchanging information. In such way, building a sort of connection bridging these two
models is clearly a need. To this point, we aim to define a system to extract data regardless of the nature of their model and make
one query enough to retrieve data from different models, which are XML and relational in our case. Accordingly, users do not
have to be familiar with multiple query language syntax at a time, they can extract data represented in both models by any query
language, even if it is not the correspondent query language of the model in question.
