    extra fields while design of tables...

    Is it a good practice to keep some extra columns in the tables giving a room of thought that there might be a reason to use those fields later down the road.
    Just thinking of some performance issues.
    Thanks,
    shankar.

    Not really, esp. if you are using Oracle8 or a higher version, where you can add columns.

    I wouldn't personally choose that option. Because I can at any time add and extra column to a table using alter table add. Suppose I don't get to use, I would just be wasting space.

    But the choice is up to the design individual.

    If you do not use a column, just drop it. In general, no extra columns are maintained in the schema.
