What Robin is saying - set the database metadata (column descriptions) to values that actually enforce datatyping, like DATE, NUMBER(5). When you insert data, the db will check to be sure data is correct in terms of typing. Instead of you having to do it manually later on. There are constraints that you use as well when you first create your new table - like NOT NULL, UNIQUE (for keys), and dependancy - key in child table has to match existing column value in parent table.

If you allow weak datatyping, like setting a column to allow any text, then anything can and will be inserted into that column. And you have a mess to clean up.
