• Security Best Practices: Protecting sensitive financial information
• Advanced UI Patterns: Complex forms with validation and error handling
• Reporting Systems: Financial summary and trend analysis

Key Features to Implement:

Dashboard Analytics

• Visual Metrics: Graphical representation of key financial data:
  • Monthly contributions for current year
  • Year-over-year contribution totals
  • Contribution growth/decline trends
  • Average contribution amounts by month and year

Transaction Management System

• Comprehensive Input Form:

  • Transaction date with calendar picker (bonus)
  • Payee name validation
  • Monetary amount with proper formatting
  • Memo field for additional details
  • Form controls: Clear, Add, Modify, Delete

• Transaction Ledger:

  • Tabular display of all contributions
  • Sortable columns with visual indicators (bonus)
  • Individual transaction modification capabilities
  • Bulk operations and filtering

Data Validation and Security

• Input Validation:

  • Date format verification
  • Required field enforcement
  • Numeric amount validation
  • Consolidated error messaging

• Security Requirements:

  • No sensitive data in local storage
  • Secure data persistence options (files/databases)
  • Data encryption for transaction storage

User Experience

• Navigation System: Hamburger menu with Dashboard/Transactions
• Responsive Design: Mobile-friendly interface
