Corporate data are divided vertically or horizontally in the network by their functions. In this study, we propose a TMDR-based query conversion method to access these data by means of integration. TMDR is a repository that combines MSO for schema integration and Topic Maps for semantic integration of data. In methodology, the global query is created for global processing using TMDR, and the resulting global query is broken down into local schema to access distributed systems in a network, enabling integrated access. We propose a method of converting global query and local query for this purpose.
