What this category's data looks like
In the laboratory hazardous chemicals procurement and ledger scenario, three types of materials enter the deployment, operations, and application handover function: hazardous chemicals procurement applications, usage registrations, and inventory ledgers. Procurement applications contain product name, specification, quantity, application date, and approval signature; usage registrations contain the person using the materials, usage date, purpose, and issuance signature; inventory ledgers contain the balance quantity, batch, inbound and outbound dates, and custodian signature. These materials are generated by the business side by shift or batch, and their update cadence is synchronized with procurement and usage actions. When entering this function, the three types of materials serve as handover-ready business records, and together with the connection configuration of the deployment environment they form a verifiable deployment status and operation records, for operations staff or the next shift to check item by item according to the handover sheet.
Configuration and implementation checks
This step is executed by the connection configuration of the deployment environment (server side), not by the capability of a model node, and outputs whether the connection is available (service startup result and connection logs). The handover-ready deployment status and operation records are then completed by the deployment handover and subsequent business processing. The connection addresses of the main business database, log database, cache, and vector database are configured separately via environment variables; if the log database is not configured separately, it reuses the main database.
| Object | Check | Verification action |
|---|---|---|
| Hazardous chemicals procurement application | The application form and inventory ledger should be consistent in product name, quantity, and date, and signatures and receipts should be complete | Check the product name, quantity, date, and signature of the application form and ledger item by item, and record discrepancies |
| Usage registration | The usage registration and inventory ledger should correspond in usage quantity, date, and person using the materials, and the issuance signature must not be missing | Check the correspondence between the usage registration and the ledger according to the handover sheet, and inspect signatures and receipts |
| Inventory ledger | The balance quantity, batch, and inbound and outbound dates are traceable, and the version is synchronized with the previous shift's records | Check the balance, batch, and dates against the previous shift's ledger, and confirm the version is consistent |
| Deployment connection configuration | The connection addresses of the main business database, log database, cache, and vector database are consistent with the deployment instructions and connectable | In the deployment environment, check the values of MONGODB_URI, REDIS_URL, and PG_URL against the database addresses, and review the startup log connection results |
Three common errors
- Symptom: The name, quantity, and date of the same procurement record do not match between the application form and the inventory ledger. Cause: The two materials were entered separately and were not checked item by item according to the handover sheet.
- Symptom: The usage quantity or date in the usage registration and inventory ledger is inconsistent. Cause: The usage action and ledger update are not synchronized, and the issuance signature or receipt is missing.
- Symptom: After startup, the logs continuously report connection timeouts, and retrieval reports vector database errors. Cause: The connection variables are inconsistent with the actual database addresses, or the log database and main database are mixed up.
How to verify the setup
This function's acceptance: connect once to the main business database, log database, cache, and vector database item by item, check the connection results in the startup logs, and verify that the values of MONGODB_URI, REDIS_URL, and PG_URL are consistent with the database addresses.
Business test: check once item by item according to the handover sheet, see which record is missing, and focus on checking the fields, dates, and signatures of procurement applications, usage registrations, and inventory ledgers.
- In the deployment environment, check the connection variable values of the main business database, log database, cache, and vector database, confirm they are consistent with the deployment instructions, and review the service startup results and connection logs.
- Check the product name, quantity, date, and signature of procurement applications, usage registrations, and inventory ledgers item by item according to the handover sheet, record missing items, and hand them over to the next shift.
