For my AngularJS applications I use PHP as my server side language which mainly interacts with the MySQL or Oracle database. I need to created a database helper class using PHP to collect all recurring database operations into a single class, so that we can easily use it whenever we need to select, insert, update or delete record from database.
This database helper class generate the CRUD statements dynamically and always output the response in a standard format. Hence reducing the recurring tasks load on programmer. This also makes bug tracking task easy as everything stores in a central location.
