Database Example Snapshot

Open

Type of Request : PUT

Required inputs : id is the only required input for this API. It must be integer.

So, you must need to enter the id and the fields you want to update in database

All this data should be given in the format of JSON. You can find it in BODY->RAW->JSON

E.g.

WorkFlow:

1. User makes an Insert request with some inputs.

2. Hits the API.

3. If id is not present then it will return bad request response with message that id is not present.

4. If id is present and it is not an integer then also it will throw error showing that is doesn’t have integer value.

5. If id is integer and id is not present in the database then it will throw error showing message that id is not present in the database.

6. If all things are right then it will call the service layer passing the JSON data in the form of a map.

7. Service layer will make a Model and then fill the id and other fields received from the request.

8. Then service layer will call the Dao layer.

9. Dao layer get the row corresponding to that id after that it will check all the fields of Model received from the service layer. If it is not null then it will update it into the row. And finally it update the model and commit it to the database.

10. Then it will return 1 to the service layer if id was present in the database. And if the id was not present in the database then it will return -1 to the service layer.

11. Then service layer return the same response to the Endpoint. And then endpoint send an error(id not found in the database) if it gets -1 as response from service layer. And if it get 1 as response then it will return to the user that data is updated successfully.

12. Most of the error handling is done. Remaining is in progress.s
