# CMA Database Query Report
|
||
|
||
**Database:** `/root/cma-management/backend/cma.db`
|
||
**Format:** SQLite
|
||
|
||
## Database Schema Overview
|
||
|
||
The database uses MySQL in production (via SQLAlchemy) but a local SQLite copy exists at `cma.db`.
|
||
Based on source code analysis (`app/models/__init__.py`, `scripts/seed_cost_data.py`), the relevant tables are:
|
||

## How to Run Live Queries
|
||
|
||
A query script has been prepared at:
|
||
```
|
||
/root/cma-management/backend/scripts/query_cma_db.py
|
||
```
|
||
|
||
Run it with:
|
||
```bash
|
||
cd /root/cma-management/backend
|
||
python3 scripts/query_cma_db.py
|
||
```
|
||
|
||
Or use sqlite3 directly:
|
||
```bash
|
||
sqlite3 /root/cma-management/backend/cma.db ".tables"
|
||
sqlite3 /root/cma-management/backend/cma.db "SELECT * FROM actual_costs;"
|
||
sqlite3 /root/cma-management/backend/cma.db "SELECT * FROM standard_costs;"
|
||
sqlite3 /root/cma-management/backend/cma.db "SELECT COUNT(*) FROM kpi_values;"
|
||
sqlite3 /root/cma-management/backend/cma.db "SELECT COUNT(*) FROM budget_plans;"
|
||
```
