   The static fields always based on your client requirement. In General Customer-Id is static, other fields should be have the option to change. not everyone well in typing, the mistakes may happen any time. so the mandatory field's of Customer must have the update option.

 

Thank You. 

Thanks. This is the interview question asked by one of the interviewer. 

Consider online shopping project, if i want to make a table for customer then in that what are the attributes i supposed to be declared as a static.

For eg take name attribute. We can not define it as a static, since it varies.
