Study Notes
System Integration
- Involves combining various subsystems or components into a unified system for cohesive functionality.
- Key in information technology for linking different computing systems and software applications.
Types of Integration
Data Integration
- Combines data from different sources to create a unified view across an organization.
- Techniques include:
- Data virtualization: Provides access to data without physically relocating it.
- Middleware data integration: Standardizes data using middleware for a master data pool.
- Application integration: Enables data movement and synchronization between different applications.
- Manual data integration: Custom code used for one-time integrations without automation.
- ETL (Extract, Transform, Load): Extracts data from various sources, transforms it for compatibility, and loads it into target databases.
Process Integration
- Focuses on aligning and automating business processes for improved efficiency.
Technology Integration
- Combines hardware and software technologies, utilizing APIs and middleware for system communication.
Organizational Integration
- Aligns different departments within an organization for effective collaboration.
- Requires changes in management practices and organizational structure.
Challenges in Integrating Heterogeneous Systems
- Compatibility issues: Variations in technology stacks and protocols create communication barriers.
- Security and compliance: Increased vulnerability to data breaches necessitates strict adherence to security protocols.
- Data consistency: Maintaining accurate data across integrated systems poses significant challenges.
- Performance and scalability: Integration can affect system performance and scalability under increased loads.
- Maintenance and upgrades: Complexity arises from differing update cycles among integrated systems.
System Architecture
- Refers to the framework conceptualizing software systems, defining component interaction, data flow, and organization.
- A well-structured architecture ensures scalability, maintainability, and compliance with performance/security standards.
Architectural Styles
-
Monolithic architecture: All components tightly coupled in a single unit.
- Pros: Simple development and testing.
- Cons: Difficult to scale and modify.
-
Client-server architecture: Divides system into client and server components.
- Pros: Clear separation, scalable servers.
- Cons: Complexity with multiple clients/servers, potential bottlenecks.
-
Microservices architecture: Comprises loosely coupled services communicating via APIs.
- Pros: Highly scalable, independent deployment, improved fault tolerance.
- Cons: Management complexity and monitoring needs.
-
Layered (n-tier) architecture: Divides system into distinct layers (presentation, business logic, data access).
- Pros: Enhanced modularity, easier maintenance.
- Cons: Rigidity and potential performance overhead.
-
Event-driven architecture: Focuses on producing, detecting, and responding to events.
- Pros: Scalability and flexibility for unpredictable workloads.
- Cons: Complexity in event management and debugging challenges.
Components of System Architecture
-
Modules: Distinct functional units within the system, allowing for independent development and maintenance.
- Example: E-commerce system could include modules for user authentication, product management, and order processing.
