Dashboard & Reporting System
Transform raw database data into insightful KPIs, charts, and reports — with caching for speed and RBAC for security.
🔄 Dashboard Data Architecture
📋 Dashboard Flow Step by Step
1
👤Admin/User
Access dashboard page → Select date range, filters, and metrics to view
2
🌐Frontend
Send API request with filters (date_from, date_to, group_by, metric)
3
🔐API Server
Check permission (RBAC) → User can only see their own data or all (admin)
4
⚡Cache Layer
Check Redis cache first → Return cached result if TTL still valid (5-15 min)
5
🗄️Database
Execute aggregation query: SUM, COUNT, AVG, GROUP BY, with proper indexes
6
⚙️ETL Layer
Transform raw data: calculate trends, percentages, growth rates, comparisons
7
💾Cache Layer
Store result in Redis with TTL → Reduces DB load on repeated requests
8
📊Frontend
Receive structured data → Render charts (bar/line/pie) + KPI cards + tables
9
🔄System
WebSocket or polling for real-time metrics (orders per minute, active users)
10
📤Admin
Apply filters → Export to CSV/Excel/PDF → Schedule automated reports
