چکیده
Peer data management systems (PDMS) has made available to almost all computer users to have a basic physical capability of sharing data. Meanwhile, problem of data sharing from multiple locations has raised significant attention since the actual data is stored in users' data sources at peers' location [KP05]. Usually, a logical virtual mediated schema is used to create data views that describe contents of the data sources. View is a stored query, which is formulated over data sources schemas in order to get access to the actual data sources. Thus, any user query is formulated over this view.
