Architecture & Coding Repository name: coding-
You have to design and build the system that allows to receive and collect data about energy consumption from different villages. As a result, your system should, on demand, give out the consumption report per village for the last 24h. As a result of your work, we expect the end-to-end design of the system (a model, system architecture, technology, and frameworks choice, testing strategy, etc.). We would also like to see your code for the whole system or reasonable part of it. Since our main programming language is Java, it would be nice if you implement this solution using it. However, if you have a project (with a task of similar complexity), then you can share it with us as well, instead of coding this task. In this case please create a statement/document explaining the problem that is being solved with it, this project should speaks for your code skills :-).
Consider that your system has an API that is called by electricity counters:
POST /counter_callback { "counter_id": "1", "amount": 10000.123 }
To get information additional information about the counter you have to call the following external API:
GET /counter?id=1 { "id": "1", "village_name": "Villarriba" }
As a result, it's expected that your system will expose the following API:
GET /consumption_report?duration=24h { "villages": [ { "village_name": "Villarriba", "consumption": 12345.123 }, { "village_name": "Villabajo", "consumption": 23456.123 } ] }
Note : All the unit test cases where written and the code coverage has been done.
