Challenge: Develop a Data Aggregation System

Problem statement

In the domain of Internet of Things (IoT), various devices generate data in different formats and protocols. Your task is to design a data aggregation system that collects data from diverse IoT devices, standardizes the data, and stores it in a centralized database for analysis and monitoring.

Tasks

Perform the tasks below to complete this challenge:

Generate device interfaces

• Create abstract interfaces for different types of IoT devices, such as TemperatureSensor, HumiditySensor, and MotionSensor.

• Define concrete classes that implement these interfaces for different devices, using simulated data for testing.

Develop device adapters

• Design adapter classes for each type of IoT device, adapting their unique data formats to a common data structure.

• These adapters should implement the respective device interfaces and internally handle the translation of device-specific data to the standardized data structure.

Build the data aggregation system

• Create a DataAggregator class that manages the collection of data from various IoT devices.
• The DataAggregator should accept instances of the device adapters and collect data from each device using the common data structure.
• Store the standardized data in a centralized database for further analysis.

Your solution will implicitly utilize the Adapter design pattern to handle the diversity of IoT device data formats.
