What's the best control used for maintenance of DB

It depends on this questions:

1) How clean you need the data? 100%?
2) How reliable are the Persons who work on the data
3) How many data you have

If your answer for 1) is 100% then you should have 2) VERY

If 2) is VERY then make a datagrid AND Formview. The datagrid should have the option that the user can make by himself ANY sortorder. This helps the user to find bad records.

If 3) is more than 10.000 then you should impement some code that check the new records for existing records. Check for type mismatch and for lazy errors. Maybe autofill the fields if you get the idea what the user want to write in the current field.
