### Ex $2$

Build a real$-$time data processing system that receives large amounts of data from multiple sources, processes it in real$-$time, and stores it in a database. The data can be of different types $($e$.$g$.$ text, audio, video$)$ and needs to be processed in different ways depending on the type.

Use the factory method pattern to create different data processing modules for each data type. The system should be easily expandable to add new data types and processing modules in the future.

Here are the steps to complete the exercise:

$1.$ Define the Data class that will serve as the base for all data types. It should have the following properties:

$-$ Type $($string$)$

$-$ Content $($object$)$

$2.$ Define an abstract DataProcessor class that will serve as the factory for creating data processing modules. It should have the following abstract method:

$-$ createDataProcessor$($Data data$)$

$3.$ Create concrete DataProcessor classes for each data type $($e$.$g$.$ TextDataProcessor, AudioDataProcessor, VideoDataProcessor$)$ that extend the DataProcessor class and implement its createDataProcessor method to create a specific data processing module. Each processor should process the data in a unique way depending on its type.

$4.$ Define the Content objects that will be used to populate the corresponding property of the Data class for each data type.

$5.$ Create a DataProcessorCreator class that will use the DataProcessor to process the data. It should have the following methods:

$-$ setProcessor$($DataProcessor$)$

$-$ processData$($Data data$)($calls the createDataProcessor method of the processor to process the data$)$

$6.$ Use the DataProcessorCreator and the concrete processors to process the incoming data in real$-$time and store it in the database.

$7.$ Implement a system for allowing the addition of new data types and processing modules in the future, by creating new concrete processors that extend the DataProcessor class and implement its createDataProcessor method to create a specific data processing module.

Note: You can use any programming language you are comfortable with to complete this exercise.
