Re: calculated field

A basic rule of database design is to minimise redundancy. And, every time to store a calculated result, you run the risk of skew. So unless the calculation is costly enough to justify storing the result, it's most always preferable to put such calculations straight into your queries, either as a function, or as inline sql, or as a column in a View (indeed that's mainly what Views are for).
