# Summary: UMKM Module Implementation

## Accomplishments
- Successfully migrated the database to include `Umkm`, `ProdukUmkm`, and `PenjualanProduk` tables.
- Implemented a complete set of CRUD API endpoints for UMKM, Products, and Sales.
- Developed a comprehensive Dashboard API providing KPIs, sales summaries, top products, and detailed stock analytics.
- Integrated the new module into the existing `ekonomi` router.
- Verified the implementation with `tsc` to ensure type safety.

## Stock Management Logic
- Creating a sale decrements product stock.
- Updating a sale adjusts stock based on the difference in quantity.
- Deleting a sale increments stock back.

## Next Steps
- Implement frontend UI for the UMKM module.
- Add more comprehensive tests for the stock management logic.
