Mini System Integration: From Data to Functionality
Welcome to this laboratory demonstration on System Integration! In this video, we explore how two independent software subsystems can communicate using the Data Integration model.
🔍 The Scenario:
Subsystem A (Data Provider): A Java module that maintains an internal list of students and their grades.
Subsystem B (Consumer): A "Grade Reporter" that consumes data to generate formatted reports.
Integration Model: Data Integration — Subsystem A exports its data as a JSON-like string, and Subsystem B ingests, parses, and utilizes that data.
⚙️ What You'll See:
A pure Java implementation (no external libraries or frameworks).
How data is structured, exported, and parsed between systems.
A live demonstration of the code running and producing output.
💡 Key Takeaways & Reflection:
Understanding the decoupling of systems through data sharing.
Identifying pain points such as data format mismatches and transformation (ETL) requirements.
Real-world connections to school enrollment systems, financial software, and enterprise application integration.
Perfect for students learning about software architecture, enterprise integration patterns, or preparing for laboratory submissions.
