Topic                                   Course
---------                               ----------
ID:String::Primary Key                  ID:String::Primary Key
NAME:String                             NAME:String
DESCRIPTION:String                      DESCRIPTION:String
                                        TOPIC:Object of Topic entity

Here TOPIC in Course entity is object of Topic entity and it creates a ONE-TO-MANY relationship, where ONE Topic may have MANY Courses.

Mapping

Note: Since the project is just for practis, the url may not respond some time. USE POSTMENT TO TEST THIS REST API

1. To GET all the topics in the server visit fallowing url

   https://young-bayou-11361.herokuapp.com/topics

2. To POST any new topic we need to send a POST request along with some payload contaning Content-Type flag in header set to application/json. To send/POST data, use following url (same as used to GET).

   https://young-bayou-11361.herokuapp.com/topics

    POST
    In Header:
        Content-Type = application/json
    Body:
       {
            "id": "Java",
            "name": "Java basics",
            "description": "Learn basic Java"
       }
   

3. To PUT/Modify/Update data of a topic, we need to send PUT request with payload contaning the same Id but modified data.

    PUT
    In Header:
        Content-Type = application/json
    Body:
        {
            "id": "Java",
            "name": "Java basics",
            "description": "Learn basic Java with example"
        }
   

   If you notice, description element of Body, we see that it's been changed from

   "description": "Learn basic Java" to "description": "Learn basic Java with example"

   But id should remain same as before "id:Java"

4. To DELETE a topic we need to send a DELETE request, with Id of the specific element. Here we are sending topic Id as Java.
