==========================
Technologies we have used |
==========================
1) Springboot, the main framework for developing the RestFul API
2) Springboot web dependency for enablign the web service
3) Springboot Development Tools (DevTools) for instance update of the application.
   Using DevTools we do not need to restart the server after any changes,the changes
   will be automatically trigger, you only need to save the changes, and the server
   will be automatically restarted, it speeds up the development and remove the pain
   of restarting the server every after tiny changes. 
4) lomback is used for removing boilerplate code i.e. setters, getters, toString and etc.
   from model/entity. using @Data annotation which is lomback most famous annotation,
   we can get all free. It compresses our code, and makes it much easy to edit or maintain.
5) log4j2 is used to generate logs and create logging files in logs folder, this logging 
   framework helps us to monitor and trace the application.
