This paper aims at investigating the integration of structured data into a semi-structured environment. In particular, it introduces the Cyclic Structure Converter (CSC) system that performs this task. In CSC, correspondence assertions and integration rules provide the adequate intelligence to reconcile the (possible) heteroge_ neous semantics relative to involved information sources. CSC has also the capability to filter and process only the relevant operational data. CSC s versatility in maneuvering with di#erent data models allows it to be applied into any field, such as engineering, insurance, medicine, space science and education, to mention a few.
