Which would be the vantages/disvantages using the followings approaches to
implement calculated fields?

1. Calculated field implemented on the database with COMPUTED BY clause.
2. Get the calculated value with an expression in the SELECT clause.
3. Implement the calculated field in the client application.

Thanks.
