No, it shouldn't.  But I've just seen a lot of denormalized tables that 
result from the need to display denormalized.  Days of the week is a common 
example - the table has fields for each days of the week.  4GLs like Paradox 
and Access were prime candidates because of the simplicity of binding a UI 
form directly to a table.  Developers (I use this term loosely) would often 
take shortcuts when modeling the data, leading to, for example, tables with 
a column for each day of the week.  Not intermediate tables.
