title: Verification of SQL database
body: <p>I am currently doing a SQL assignment but a certain task has mentioned that we need to implement validation and verification for our tables in the database which we created. </p>
  
  <p>However we did not learn anything about this topic and after googling for hours I only found the check constraints which you can give in the create table statement.</p>
  
  <p>Please mention some of the TECHNIQUES of validation and verification for a SQL table or database. </p>
