Implement a class called driver or modify the existing skeleton -> have a look at SDriver.?xx +2. Implement a class called connection -> have a look at SConnection.?xx +3. Have a look at the DatabaseMetaData -> see SDatabaseMetaData.cxx + The methods which should be implemented at least are + - getTableTypes + - getTables + - getTypeInfo + - getColumns + +4. You need a statement to show/access some data -> have a look at SStatement.cxx + -> especially executeQuery() + +5. The ResultSet: without you see nothing -> look at SResultSet.cxx +6. The ResultSetMetaData needed to get some information about what are waiting for us + -> look at SResultSetMetaData.cxx + +7.
