Unit 03: LO 4 - 4.4 - Link Information System to a Data System

Linking an information system to a data system securely and effectively is like building a secure bridge between two islands, so data can travel back and forth safely and quickly. Below are ways to perform each of the required tasks.

Ensuring Secure Connection

• VPN or Private Network: Establish a Virtual Private Network (VPN) or private network link between the systems. This is like creating a private, secured lane on a public bridge.

• Use HTTPS or Secure APIs: Always use HTTPS protocols or secure API keys for fetching data between systems. These mechanisms are like security checkpoints on either side of your bridge.

• Firewall Rules: Set up firewall rules to allow only specific IP addresses to request data. This prevents unauthorized traffic.

Requesting Data Using an Appropriate Information System

• Database Queries: If you have access to both systems' databases, you can use SQL queries to pull data.

Displaying the Data in the Information System

• Dashboard Widgets: If you're using an Information System like a dashboard, widgets can display real-time data fetched from the data system.

• MS SharePoint Integration: If your information system is based on MS SharePoint, you can link an Excel file with live data to a SharePoint site.

• Google Gauges with Spreadsheets: If you're using Google Sheets for your information system, you can link it to Google Gauges for visual representation of your data.

Methods to Accomplish This

• Simulation Software (Packet Tracer): If you're in the testing phase, using simulation software like Packet Tracer can help you mock up your network architecture and test the security and efficiency of data transfers.

• Linking to MS SharePoint: As mentioned, SharePoint allows you to create interactive dashboards where you can link live data files.

• Google Gauges with Spreadsheets: This is an easy and quick way to visualize real-time data, especially for smaller projects.

By performing these steps, you'll effectively link your information system with your data system, ensuring that data can move securely and be displayed effectively. This is similar to building a secure and efficient bridge between two islands that allows for smooth transport of goods (in this case, data).
