Database Connections and Operations for Teacher Qualification Exams and Certification: Coordinate Operations and Application Handover

Teacher Qualifications: 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 category's data covers three core types of materials: written and interview registration forms for teacher qualification exams and certification, Mandarin proficiency certificates, and medical examination forms. The sources are exam institutions and certification institutions, and the update cadence advances with batches and certification cycles. Registration forms carry registration information and subjects, Mandarin proficiency certificates carry levels and test dates, and medical examination forms carry medical examination conclusions and signatures. When the materials enter the deployment, operations, and application handover function, each plays a different role: registration forms correspond to business records in the primary business database, while Mandarin proficiency certificates and medical examination forms correspond to attachments and status records in the log database or the primary database. Field characteristics include name, ID number, date, level, conclusion, and signature receipt. Only when version, connection, and task records are consistent can a handover-ready deployment state and operation records be formed.

Configuration and implementation checks

This step is handled by the connection configuration of the deployment environment (server side), not by the capability execution of a model node, and outputs whether the connection is available (service startup result and connection logs). "Handover-ready deployment state and operation records" are then completed by deployment handover and subsequent business processing. The primary business database, log database, cache, and vector database can point to different instances respectively; if the log database is not configured separately, it reuses the primary database.

ObjectCheckVerification action
Primary business database connection variablePoints to the primary business database actually in use and is connectable; registration form fields, dates, and signatures are traceableIn the deployment environment, check that the variable value matches the database address, and connect once with a client
Log database connection variableConfigured separately, or left empty per the instructions to reuse the primary database; Mandarin proficiency certificate and medical examination form records are queryableCheck whether the variable is set, and verify whether the database written to by logs matches the material dates and quantities
Cache connection variableThe cache instance is connectable; task records in the handover form are not missing due to cache interruptionConnect once with a client, and check the return against the startup logs
Vector database connection variableMatches the vector database actually in use; when retrieval errors occur, the vector database can be locatedCheck the selected vector database and address against the deployment instructions, and check the retrieval logs

Three common errors

  • Symptom: The name, quantity, and date of the same record do not match between the registration form and the Mandarin proficiency certificate. Cause: The two materials are entered separately and are not checked item by item against the handover form.
  • Symptom: The medical examination form lacks a signature or receipt, yet it is marked as complete on the handover form. Cause: Signatures and receipts are not included in the verification actions, and the version is not synchronized.
  • Symptom: After startup, logs continuously report connection timeouts, and business data and logs are mixed in the same place. Cause: Connection variables only indicate whether the service can connect; they cannot infer the read/write location of business data.

How to verify the setup

This function's acceptance: connect once to the primary business database, log database, cache, and vector database item by item, and check the connection results in the startup logs; in the deployment environment, check that the values of the three variables MONGODB_URI, REDIS_URL, and PG_URL match the instance addresses.

Business test: check item by item once against the handover form to see which record is missing; compare the fields, dates, and signatures of the registration form, Mandarin proficiency certificate, and medical examination form item by item. Handover is possible only when version, connection, and task records are consistent.

  • Check the fields, dates, and signatures of the registration form, Mandarin proficiency certificate, and medical examination form item by item against the handover form, and record missing items.
  • Check MONGODB_URI, REDIS_URL, and PG_URL against the deployment instructions, and confirm that the connection results are written into the operation records.
