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:

(1) actual_costs — All Records

Schema (from StandardCost / ActualCost model):

Column Type Description
id INTEGER PK Auto-increment
period VARCHAR(20) Period (e.g., "2026-04", "2026-05")
product_code VARCHAR(20) Product code (P001-P003, S001-S002)
product_name VARCHAR(200) Product name
cost_type VARCHAR(20) material/labor/overhead
item_name VARCHAR(200) Cost item name
actual_quantity FLOAT Actual quantity
actual_price FLOAT Actual unit price
actual_cost FLOAT Total actual cost = qty × price
source VARCHAR(20) Data source ("manual")
version VARCHAR(20) Standard version (nullable)
remark TEXT Notes (nullable)
created_at DATETIME Auto timestamp

Expected records (if seed was run): 25 rows

(3) kpi_values & budget_plans — Data Check

kpi_values

Schema (from KPIValue model):

Column Type Description
id INTEGER PK Auto-increment
kpi_id INTEGER (FK→kpi_definitions) KPI reference
period VARCHAR(20) Period (e.g., "2026-05")
actual_value FLOAT Actual KPI value
source_type VARCHAR(20) erp/excel/manual
source_batch VARCHAR(100) Import batch (nullable)
data_status VARCHAR(20) pending/verified/error
calculated_at DATETIME Auto timestamp
remark TEXT Notes (nullable)

Status: kpi_values is populated when ERP sync runs or via manual data entry. Contains KPI actual values linked to kpi_definitions.

budget_plans

Schema (from BudgetPlan model):

Column Type Description
id INTEGER PK Auto-increment
period VARCHAR(20) Budget period
product_code VARCHAR(20) Product code
product_name VARCHAR(200) Product name
cost_type VARCHAR(20) material/labor/overhead
planned_amount FLOAT Budgeted amount
remark TEXT Notes
created_at DATETIME Auto timestamp
updated_at DATETIME Auto timestamp

Status: budget_plans holds budget plan data by product and period, used for variance analysis against actual costs.

How to Run Live Queries

A query script has been prepared at:

/root/cma-management/backend/scripts/query_cma_db.py

Run it with:

cd /root/cma-management/backend
python3 scripts/query_cma_db.py

Or use sqlite3 directly:

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;"
