1. Install JAVA JDK 11, MAVEN in your machine.
2. Install PostMan client to test the Endpoints.
3. Install POSTGRESQL and PGAdmin Client.

API Reference: POST : http://localhost:8080/saveTemperature GET : http://localhost:8080/getHourlyData GET : http://localhost:8080/getDailyData

Sample JSON for POST Request save_temperature.json

Tests: Please run 'mvn install' or 'mvn test' from the root folder to execute the Test Cases.
