System Integration
What is System Integration in IT?
System Integration refers to the strategic process of combining various individual subsystems into a unified, cohesive system. The goal is to ensure that all integrated subsystems function harmoniously as a single entity.
What are the 2 components of system integration?
- Subsystems: These are the individual systems or software applications that need to be combined.
- Interface: This is the point where the subsystems connect and communicate with each other.
What are the 4 types of system integration?
- Horizontal Integration: Also known as “Enterprise Service Bus (ESB)”, it involves integrating different systems through a common interface.
- Vertical Integration: This is where systems are integrated based on their functionality, forming a “silo” of systems from bottom to top.
- Star Integration (or Spaghetti Integration): Each system is connected to multiple other systems, forming a pattern like a star.
- Common Data Format: Systems are integrated by converting data into a common format that can be understood by all systems.
What are the 4 benefits of system integration?
- Efficiency: Processes are streamlined, reducing redundancies and improving workflow.
- Data Accuracy: With integrated systems, data remains consistent and up-to-date across platforms.
- Cost Savings: Reduces the overhead of managing and operating isolated systems.
- Enhanced Functionality: The combined capabilities of integrated systems offer richer functionalities.
What are the roles of system integration?
- System Architect: Designs the structure of the integrated system.
- Integration Developer: Writes the code to connect and integrate different subsystems.
- Project Manager: Oversees the integration project, ensuring it stays on track and meets objectives.
- QA Tester: Tests the integrated system for any issues or bugs.
- Business Analyst: Understands the business needs and ensures the integrated system meets those requirements.
