This advanced course explores architectures and technologies for processing continuous, unbounded streams of data. Students learn the stream processing paradigm, event time versus processing time, and work with technologies like Apache Kafka for messaging and Apache Flink or Kafka Streams for stateful computations. This skill set is vital for building low-latency systems in Zambia, such as real-time fraud detection for banks, network monitoring for ZESCO's grid, or live customer engagement analytics for Telecom companies. 25schools supports this complex topic with architectural diagrams of real-time systems, coding exercises for building streaming applications, and case studies on IoT data streams from the Mining sector, preparing students at Apex and CBU for exams and for engineering the responsive data systems of the future.

This advanced architecture course focuses on designing and implementing modern, scalable data platforms, with emphasis on the emerging Lakehouse pattern that combines the flexibility of data lakes with the management features of data warehouses. Students evaluate storage formats (Parquet, Delta Lake, Iceberg), design for performance and cost, and plan for …

This advanced architecture course focuses on designing and implementing modern, scalable data platforms, with emphasis on the emerging Lakehouse pattern that combines the flexibility of data lakes with the management features of data warehouses. Students evaluate storage formats (Parquet, Delta Lake, Iceberg), design for performance and cost, and plan for scalability and security. This strategic skill is essential for Senior Data Engineers and Solution Architects tasked with building enterprise-wide data platforms for Zambian conglomerates or government digital transformation initiatives. 25schools provides architecture blueprint templates, comparative analyses of technology stacks, and design challenges based on scaling needs of Zambian enterprises, preparing students for complex exam questions and leadership roles in technology implementation.

This course provides an in-depth, engineering-focused mastery of SQL, the essential language for managing and manipulating relational data. Students progress beyond basic queries to advanced topics including complex joins, window functions, query optimization, indexing strategies, and stored procedure development. For Data Engineers in Zambia, proficiency in writing efficient, production-grade SQL …

This course provides an in-depth, engineering-focused mastery of SQL, the essential language for managing and manipulating relational data. Students progress beyond basic queries to advanced topics including complex joins, window functions, query optimization, indexing strategies, and stored procedure development. For Data Engineers in Zambia, proficiency in writing efficient, production-grade SQL is critical for building data warehouses, optimizing ETL processes for financial institutions like Zanaco, or managing customer data for Telecom giants. 25schools supports this technical skill development with a comprehensive library of advanced query exercises, performance tuning guides using real Zambian database scenarios, and exam preparation materials that challenge students at Apex and other universities to think like engineers, not just analysts, ensuring they are exam-ready and job-market competitive.
