Study Notes
System Integration
- Combines interrelated elements to achieve common objectives.
- Key Aspects:*
- Interoperability: Enables effective communication between different systems.
- Data Integration: Maintains information consistency across various systems.
- Process Integration: Streamlines operations for improved efficiency.
- Interface Management: Develops communication systems, such as APIs, for inter-system interaction.
- Middleware: Acts as a bridge to connect disparate systems.
- Legacy System Integration: Facilitates the use of older systems alongside modern technology.
- COTS Integration: Leverages Commercial Off-The-Shelf products to enhance system functionality.
- Scalability and Flexibility: Adapts to growth and changing requirements.
- Security and Compliance: Ensures adherence to regulations and standards.
- Types of System Integrations:*
- Horizontal Integration: Links systems across different organizational departments.
- Vertical Integration: Integrates systems at various levels within a single department.
- Star Integration: Forms a web of connections by linking every system to each other.
- Point to Point Integration: Directly connects two systems for data exchange.
- Common Data Format: Utilizes a standardized data format to simplify exchanges.
- Benefits:*
- Improves overall efficiency within operations.
- Enhances data quality through consistent integration.
- Results in cost savings by optimizing resource use.
- Provides a better customer experience by streamlining services.
- Increases organizational agility in operations and responses.
- Challenges:*
- Complexity: Particularly with integrating legacy systems.
- Cost: High expenses associated with integration efforts.
- Security Risks: Vulnerabilities that may arise during integration.
- Change Management: Difficulties in managing organizational changes.
System Architecture
- Defines the high-level structure of a system, serving as a blueprint for its behavior and design.
- Components:*
- Components: Individual modules responsible for specific functionalities.
- Connections: Facilitate communication and data exchange among components.
- Interfaces: Specify interactions ensuring component compatibility.
- Data Flow: Optimizes performance by managing data movement.
- Subsystems: Interconnected parts that work towards achieving system objectives.
- Standards and Protocols: Maintain consistency and interoperability across system parts.
- Constraints: Define restrictions within which the system must operate.
- Types of System Architecture:*
- Monolithic Architecture: A single-unit design with no separation of functionalities.
- Layered Architecture: Each layer has distinct responsibilities, promoting separation of concerns.
- Service-Oriented Architecture (SOA): Increases flexibility and scalability through reusable services.
- Microservices Architecture: Allows independent deployment and scaling of services for improved agility.
- Client-Server Architecture: Common in network-based applications, featuring distinct client and server roles.
- Event-Driven Architecture: Prioritizes asynchronous communication among components.
- Distributed Architecture: Spreads over multiple locations, enhancing reliability while managing data consistency.
- Benefits:*
- Provides clarity and a better understanding of system components.
- Enhances scalability and flexibility to adapt to future needs.
- Increases efficiency and performance of system operations.
- Facilitates maintainability and extensibility for future upgrades.
- Aids in effective risk management across system designs.
