<source lang="csharp">using System; using System.Data; using System.Data.rumon; using System.Data.SqlClient; class MainClass {

 static void Main(string[] args)
 {
   SqlConnection SConn = new SqlConnection("Data Source=(local); Initial Catalog = CaseManager; Integrated Security=true");
   SqlDataAdapter da = new SqlDataAdapter("SELECT ID, FirstName, LastName FROM Employee", SConn);
   DataSet ds = new DataSet();
   DataTableMapping custMap = da.TableMappings.Add("Employee", "MyDatabase");
   custMap.ColumnMappings.Add("ID", "Number");
   custMap.ColumnMappings.Add("FirstName", "first name");
   custMap.ColumnMappings.Add("LastName", "last name");
   da.Fill(ds);
 }
