title: Is it good to use check constraints for business rules
body: <p>Currently we are using check constraints for business rules implementation, but I want to know if we should implement business rules in SQL or in the business logic layer (C#). I have searched on the net and found that check constraints are good to use. </p>
  
  <p>Please let me know if someone knows more detailed information about it. One more thing is that the data can be pumped into my database using a mobile application and also using a web application.</p>
