title: Use Properties file or database to store values which is best approach?
body: <p>Application was developed with multi-tenant support in which i need to send SMS to the user where i need to append the country dialing code with the user mobile number. </p>
  
  <p>My question, having a separate column to store the country dialing code in the country table is good approach or to have the country code in the properties file is a good approach ? </p>
  
  <p>In general what kind of values we will store in properties file (like  DB configuration settings)?</p>
