Database Connections and Operations for School Timetables and After-School Scheduling: Coordinate Operations and Application Handover

School Timetables: review databases for operational handover. Check source versions, input mappings and the values received by downstream nodes.

What this category's data looks like

This page addresses the deployment, operations, and application handover scenarios for primary and secondary school timetables and after-school service scheduling. The materials come from the master timetable, teacher assignment table, after-school service project table, as well as connection configuration records and operation records in the deployment environment. The master timetable carries the scheduling results for all school classes and periods, the teacher assignment table carries teaching relationships and teacher arrangements, and the after-school service project table carries project names, participating classes, and time slot arrangements. When these three types of materials enter the deployment, operations, and application handover function, they serve respectively as the business deliverables to be handed over, the scheduling basis to be verified, and the service arrangements to be confirmed, ultimately converging into a handover-ready deployment status and operation records. The update rhythm rolls by semester and week number; scheduling adjustments, project additions or removals, and teacher changes all bring new versions. Field characteristics center on dates, class names, teacher names, project names, periods, and signature receipts; version numbers and handover shifts also need to be recorded. Materials are aligned by name, quantity, and date; any inconsistency in any one place will cause the handover form to have missing items.

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 address is configured by environment variables; the main business database, log database, cache, and vector database can point to different instances respectively; if the log database is not configured separately, it will reuse the main database.

ObjectCheckVerification action
Master timetableWhether fields, dates, and signatures are complete, and whether the name, quantity, and date of the same record match across the two materialsCheck class, period, date, and signature receipt item by item against the master timetable, then compare the name and quantity of the same record with the teacher assignment table
Teacher assignment tableWhether teaching relationships, teacher names, and versions are synchronized with the master timetableCheck teacher names, assigned classes, and version numbers item by item according to the handover form, and check whether there are unsynchronized old versions
After-school service project tableWhether project names, participating classes, time slots, and receipts are consistentCheck project names and the number of participating classes, check whether signatures or receipts are missing, and compare with the dates in the master timetable
Deployment environment connection configurationWhether the connection addresses of the main business database, log database, cache, and vector database are consistent with the actual instancesIn the deployment environment, check the values and database addresses of MONGODB_URI, PG_URL, and REDIS_URL, and view the service startup result and connection logs

Three common errors

  • Symptom: The name and period of the same class do not match between the master timetable and the teacher assignment table. Cause: The two materials are updated separately, versions are not synchronized, and no item-by-item comparison was made during handover.
  • Symptom: The after-school service project table lacks signatures or receipts, and the handover form cannot be closed. Cause: Records were not supplemented after project additions or removals, and the signature step was skipped.
  • Symptom: After startup, the logs continuously report connection timeouts, and business data and logs are mixed in the same place. Check: The instance pointed to by the connection variable is inconsistent with the actual database. Logs use the primary database when no separate log database is configured; inspect the actual log destination separately.

How to verify the setup

Acceptance of this function: 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 confirm that the instances pointed to by MONGODB_URI, PG_URL, and REDIS_URL are reachable.

Business test: Check once item by item according to the handover form, see which record is missing, and verify the names, quantities, dates, and signature receipts of the master timetable, teacher assignment table, and after-school service project table.

  • In the deployment environment, check the values and database addresses of MONGODB_URI, PG_URL, and REDIS_URL, and view the service startup result and connection logs.
  • Check the names, quantities, dates, and signature receipts of the master timetable, teacher assignment table, and after-school service project table item by item according to the handover form, record missing items, and hand over to the next shift.
