Today, we mainly describe the correct implementation of connecting SQL Server databases to the DB2 connection Server. We all know that the interconnection between different database platforms is generally called a heterogeneous service, currently, different databases can achieve such Heterogeneous Interconnection, but the specific implementation technologies of different vendors are different, such:
