To database or not to database
                            
                         
                        
                     
                 
                
                    I am needing to build a simple time punch application for a mobile phone.  I know that there is sqlce and all, but I'm wondering if there is a simpler approach than the one I am about to take.  So far I'm thinking a sql database on the mobile phone, with a data table.  Each day will have a unique record to record time in, lunch in, lunch out, and time out.  I'm also trying to figure out how I want to control the status of the clock in/out.
Should I be thinking SQL or not?  Is there a filebased approach that would work better for what I am doing?  I will need to query time records and so forth.
Thanks!
