Study Notes
- Systems Integration connects separate computing systems for communication.
- It integrates hardware, software, and data for a cohesive system with specific functions.
- Smoothly exchanging data through systems integration improves data management.
Reasons for Integration
- Improved Efficiency: Eliminates redundancies and streamlines processes
- Improved Data Sharing: Facilitates data sharing across departments for better decision-making and collaboration
- Cost Savings: Reduces the need for multiple systems and their associated expenses.
- Better Compliance: Provides a unified data view for regulatory compliance and correct system configuration
- Better Monitoring and Reporting: Enhances the ability to monitor performance and identify issues.
- Better Decision Making: Offers a unified data view and facilitates data analysis.
- Competitive Advantage: Provides a more efficient system that responds quickly to market changes
Key Concepts
- American Standard Code for Information Interchange (ASCII): a standard data-encoding format for electronic communication between computers that assigns standard numeric values to letters, numerals, punctuation marks and other characters
- Before ASCII, different computer models couldn't communicate, leading to its development.
- Application Programming Interface (API): A defined and documented software interface for program interaction with a system.
- Interface: Must have stable and well-defined characteristics.
- Media: Physical or logical channels for data transmission between systems.
Physical Media
- Copper Wires
- Fiber-optic Cables
- Wireless Media
Logical Media
- Network Protocols: Rules for connected devices to communicate across a network.
- Protocols enable communication irrespective of differences in software, hardware, or internal processes
- Examples: Transmission Control Protocol (TCP), Internet Protocol (IP), Hypertext Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP), Internet Message Access Protocol (IMAP) and File Transfer Protocol (FTP).
- APIs
- Cloud-based Services: Applications hosted on the vendor’s server, available remotely.
Middleware
- It is a software that enables communication and data exchange between different systems or applications.
Functions of Middleware
- Data Integration: Extracts, transforms, and loads data into a consistent format.
- Service Integration: Provides a unified interface for systems to be accessed and controlled consistently.
- Security: Offers authentication and access control for integrated systems.
Protocol
- Rules governing electronic data exchange between devices.
- Devices must use the same protocol to exchange data.
- Examples: Transmission Control Protocol (TCP), Internet Protocol (IP), User Datagram Protocol (UDP), Hypertext Transmission Protocol (HTTP) and File Transfer Protocol (FTP).
- System: Interacting components working to achieve a common goal
- A system can include hardware, software, and/or people, ranging from simple devices to global networks.
Open Systems Interconnection (OSI) Model
- Networking reference model for system communication
- Physical Layer: Transmits raw bit stream.
- Data Link Layer: Defines data format on the network.
- Network Layer: Determines the physical data path.
- Transport Layer: Transmits data using protocols like TCP and UDP.
- Session Layer: Manages connections, controlling ports and sessions.
- Presentation Layer: Ensures usable data format, includes data encryption.
- Application Layer: Human-computer interaction for network service access
Types of Integration
- Legacy System Integration: Connects older systems with newer technologies.
- Legacy systems are often built using outdated technologies that may not communicate with newer systems
- Examples: legacy financial, CRM, and inventory management systems.
- Third-party System Integration: Connects systems from different organizations.
- Business-to-business Integration: Connects systems between businesses to automate processes and data exchange.
- Big Data Integration: Extracts, transforms, and loads data into a big data platform.
- Allows all data to be combined into a single view for reporting and analysis
- Cloud Services Integration: Integrates applications into cloud services for access across multiple devices over a network or the internet.
