Database Transformation

Problem Statement

• Users are unsure if the transformation is working
• No progress indication leads to poor user experience
• May result in users refreshing the page or thinking the app is broken

Proposed Solution

Add loading indicators with progress information during:

1. MySQL connection testing
2. Data extraction from MySQL
3. Neo4j data insertion
4. Graph visualization loading

Alternative Solutions

No response

Use Case

• Show spinning loader during transformation
• Display current step (e.g., "Connecting to MySQL...", "Extracting data...", "Creating nodes...")
• Add progress bar for longer operations
• Disable transformation button during process
• Show success/error message when complete
