The paper addresses the problem of integrating data based on a XML-like semistructured model with a data grid architecture based on an object-oriented model. This work is continuation of the previous works on object-to-relational wrappers and covers a generic integrationp rocedure for utilizing a native Lore query mechanism f or retrieving data from X ML data s ources. A corresponding wrapper is founded on the concepts of the stackbased approach (SBA) and updatable views. The p roposed

The described wrapper makes it possible to employ the native Lorel query optimization mechanisms. A query entering the front-endo f the wrapper (object-oriented business model) is transformed and rewritten according to the SBQL optimization rules incorporated in the wrapper and then evaluated in t he native XML resource environment through the query language Lorel. The paper discusses architectural issues of such a wrapper and presents its idea through a concise example.
