Database Connections and Operations for Teacher Qualification Exams and Certification: Track Progress and Check Statistics

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

What this category's data looks like

Teacher qualification exam and certification materials include written and interview registration forms, Mandarin proficiency certificates, and medical examination forms. The sources are exam institutions and certification units, updated by batch. Registration forms record the exam subjects, exam district, date, and signature. Mandarin proficiency certificates carry the level, number, and issue date. Medical examination forms contain the examination conclusion, hospital seal, and date. When entering the progress records and statistical verification function, the registration form serves as the main record, while the Mandarin proficiency certificate and medical examination form serve as attachment materials, used to verify whether the name, quantity, date, and signature of the same record are consistent, and to form a progress table and statistical scope statement.

Configuration and implementation checks

This step is performed by the connection configuration of the deployment environment (server side), not by the capability execution of a model node. It outputs whether the connection is available (service startup result and connection logs). The progress table and statistical scope statement are then completed by deployment handover and subsequent business processing.

ObjectCheckVerification action
Written and interview registration formThe fields include exam subjects, exam district, date, and signature; the name, quantity, and date of the same record match across the two materialsCheck that the registration form and statistical table correspond item by item, and check whether signatures and receipts are complete
Mandarin proficiency certificateThe certificate number, level, and issue date are consistent with the registration form record, and the version is synchronizedCompare the certificate with the progress table, and verify the name, date, and seal
Medical examination formThe examination conclusion, hospital seal, and date are consistent with the registration form record; missing signatures or receipts must be markedCheck the medical examination form and progress table one by one, record exceptions, and state the scope
Connection configurationThe main business database, log database, cache, and vector database each point to actual instances and are connectableIn the deployment environment, verify that the values of MONGODB_URI, REDIS_URL, and PG_URL are consistent with the database addresses

Three common errors

  • Symptom: The name and date of the same record do not match between the registration form and the Mandarin proficiency certificate. Cause: During data entry, the unified fields were not checked, the version was not synchronized, and signatures or receipts were missing.
  • Symptom: The statistical total is inconsistent with the number of records in the progress table. Cause: The scope was not written in the header, and exceptions were not marked, resulting in a quantity mismatch.
  • Symptom: The startup log continuously reports connection timeouts. Cause: The instance pointed to by the connection variable is unreachable, or the log database and the main database are mixed without separate configuration.

How to verify the setup

This function acceptance: connect once to the main business database, log database, cache, and vector database item by item, check the connection results in the startup log, and confirm that MONGODB_URI, REDIS_URL, and PG_URL are available.

Business test: use one week of records to verify the total, and see whether the scope and exceptions are clearly written.

  • In the deployment environment, verify that the values of the connection variables for the main business database, log database, cache, and vector database are consistent with the database addresses
  • Use one week of records to verify the total, and check whether the scope and exceptions are written in the header
