Representing the sharing and exchanging data withmachine-readable format allows cooperative taskautomation. In this paper we propose an XML Schemaand semantic based relational data translation approach,which aims at providing a coherent and meaningful viewof the relational data and enabling distributed users tocooperate on large data volumes online. We define adirected-graph data model as the common datamodel,present a key-based relational schema reversereconstruction arithmetic to capture the full structuresand semantic constraints in relational schema, andpropose a constraints-preserving mapping algorithm totranslate relational data into the global XMLrepresentations.
