Database Connections and Operations for Enrollment Changes and Graduation Eligibility: Track Progress and Check Statistics

Graduation Eligibility: review databases for progress tracking. Check source versions, input mappings and the values received by downstream nodes.

What this category's data looks like

This page addresses the scenario of student status changes and graduation eligibility review. Materials include leave-of-absence and return-to-school applications, major transfer applications, and graduation review checklists. Sources are academic affairs system exports and offline signed receipts. The update cadence is weekly aggregation and monthly archiving. Field characteristics center on student ID, name, change type, effective date, approval node, and signature field. When entering this function, leave-of-absence and return-to-school applications and major transfer applications serve as the change details role, the graduation review checklist serves as the graduation eligibility determination role, and the progress table and statistical scope description are responsible for aligning record counts with statistical counts, and clearly stating the scope and exceptions in the table header for reference in weekly or monthly reports.

Configuration and implementation checks

This part is executed by the deployment environment's connection configuration (server side), not by the capability of a model node, and outputs whether the connection is available (service startup result and connection logs). The "progress table and statistical scope description" is then completed by deployment handover and subsequent business processing.

Three common errors

  • Symptom: The name, quantity, and date of the same leave-of-absence and return-to-school record do not match between the progress table and the graduation review checklist. Cause: The two materials are maintained separately, without cross-checking by student ID and effective date.
  • Symptom: The version of the major transfer application is not synchronized, and the old signature field and the new approval node coexist. Cause: The version number and replacement time were not recorded after the material was updated.
  • Symptom: The graduation review checklist lacks a signature or receipt, but the progress table still includes it in the total. Cause: The signature field was not made a precondition for inclusion in the table, and exceptions were not explained in the table header.

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 corresponding to MONGODB_URI, REDIS_URL, and PG_URL can connect.

Business test: use one week of records to check the total and see whether the scope and exceptions are clearly stated

  • Align leave-of-absence and return-to-school applications, major transfer applications, and graduation review checklists by student ID and effective date, and check the name, quantity, date, and signature receipt item by item.
  • State the statistical scope and exception handling in the header of the progress table, record the tokens and array length of the referenced text, register them separately, and do not perform equality comparison.
