Case Study: Event-Driven Architecture with CDC, ETL, Kafka, and .NET Technologies

This case study analyzes an event-driven system targeting the aviation industry vertical, integrating CDC, ETL, Kafka, and .NET technologies. The system manages data from aircraft, airports, meteorological stations, and other related facilities in real-time.

The near real-time event-driven infrastructure significantly enhances the efficiency and responsiveness of various stakeholders in the aviation industry. This advanced system plays a crucial role in several key areas.

  1. Faster Passenger Information: With the implementation of this infrastructure, real-time updates about flight statuses, delays, cancellations, and gate changes can be communicated instantly to passengers. This rapid information flow greatly improves passenger experience, as they are kept well-informed and can make timely decisions about their travel plans.
  2. Ground Staff Awareness: The near real-time data flow ensures that ground staff and operational teams are immediately aware of any changes or incidents, such as delays, technical issues with aircraft, or changes in flight schedules. This immediate access to information enables ground staff to react swiftly, manage resources more effectively, and provide better service to passengers and crew.
  3. Reduction in IRROPS (Irregular Operations) Costs: By leveraging this infrastructure, airlines and airports can significantly reduce the costs associated with irregular operations. The ability to quickly respond to changes and disruptions means that airlines can minimize the impact of such events, reducing compensation costs, additional staffing requirements, and resource reallocation.
  4. Predictive Analysis for Delay Prevention: One of the most groundbreaking aspects of this infrastructure is its capacity for predictive analysis. By analyzing vast amounts of data from various sources, including weather patterns, aircraft status, and airport operations, the system can predict potential delays and disruptions. This foresight enables airlines and airports to take preemptive measures, such as adjusting schedules, rerouting flights, or reallocating resources to avoid or mitigate delays.

Overall, the near real-time event-driven infrastructure in aviation is a game-changer, offering enhanced communication, improved operational efficiency, cost savings, and predictive capabilities. It represents a significant step forward in managing the complexities of modern air travel, ensuring that all parties involved in the aviation industry can operate more effectively, adapt to challenges promptly, and provide an improved experience for passengers.

Data Processing Flow and Technological Architecture

Application of CDC: Change Data Capture (CDC) is crucial for real-time recording of data changes from RDBMS components. CDC allows for continuous data collection and instant recording, crucial in the dynamic aviation environment. Data includes flight statuses, positions, meteorological data, and other relevant information. Specialized sensors and communication protocols ensure accurate and reliable data capture.

Importance of ETL Processes: Extract, Transform, Load (ETL) processes play a pivotal role in preparing data for further processing. They ensure data is consistent, reliable, and well-structured for transmission. Transformation and normalization of data are essential for efficient handling in subsequent steps.

Data Transmission Through Kafka System: Prepared data is transmitted via the Kafka system, ensuring fast and reliable data flow. Kafka's scalability and flexibility are critical for handling large volumes of data.

Data Processing with .NET: Application Services built with .NET framework receive data from Kafka. This stage includes further transformation, analysis, and aggregation of data for specific business needs. Processed data is stored in Parquet for efficient storage and fast access.

Business Logic Execution in .NET Applications: Applications Setvice executes business logic, such as analyzing flight routes, scheduled changes, and emergency responses, identifies the business related changes in the environment. The system can rapidly respond to new data and send updates to related systems and users.

Event Transmission Through Kafka System: Events generated by business logic are transmitted through Kafka, ensuring immediate notification across the aviation system.

This system offers a complex and effective solution to the challenges of the aviation vertical, leveraging the advantages of CDC, Kafka, and .NET technologies. Capable of handling real-time data, it improves the efficiency and safety of aviation operations, enhancing overall operational effectiveness and security.
