Data validation is the job of the business layer



>Hi,
>I used to read couples of about 3 tier article, and I implement it according to what I understand. I have a class, that contain ADD(), DELETE(), LOAD() , SAVE() and etc which will manipulate my vfp data. It contains Validate() method either. So, is it a data layer / data handler or business layer?
