Database Connections and Operations for Professional Qualification Exam Applications: Coordinate Operations and Application Handover

Professional Exams: 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 for the review of registration for professional and technical personnel qualification examinations. The category materials entering this function include registration forms, education certificates, and work experience certificates; the sources are registration system exports and manual uploads, and the update cadence rolls with batches and supplementary reviews. The registration form carries identity and examination subject fields, the education certificate carries the graduating institution, major, and certificate number, and the work experience certificate carries the employment start and end dates and the employer's seal. The three types of materials play different roles in the function: the registration form provides structured fields and the batch number, while the education certificate and work experience certificate provide the basis for verification. Field characteristics are concentrated in names, ID numbers, dates, quantities, and signature receipts. After the materials enter the deployment environment, the connection configuration determines whether the service can read and write them; the materials themselves are still stored according to the data model.

Configuration and implementation checks

This step is performed by the connection configuration of the deployment environment (server side), not by the capability of the 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 main 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 main database.

ObjectCheckVerification action
Registration formFields include name, ID number, examination subjects, batch number, and signature receipt; the dates must be consistent with the start and end dates of the work experience certificateCompare the name and ID number on the two materials character by character, check whether the dates and batch number come from the same source, and return it if the signature or receipt is missing
Education certificateThe graduating institution, major, and certificate number correspond to the education level filled in on the registration form, and the version is synchronized with the batchCheck the certificate number against the registration form fields, check whether the version number is updated with the batch, and register discrepancies when names or dates do not match
Work experience certificateThe employment start and end dates, employer name, and quantity are consistent with the years filled in on the registration form, and the seal and receipt are completeCheck dates and quantities item by item according to the handover sheet, check whether the seal and receipt are missing, and check whether the dates on the two materials corroborate each other
Main business database connection variablePoints to the main business database actually in use and is connectable; the value of MONGODB_URI is consistent with the database addressCheck the value of MONGODB_URI in the deployment environment, review the connection result in the startup logs, and confirm that the main database is readable and writable

Three common errors

  • Symptom: The employer name and dates for the same registration record do not match between the registration form and the work experience certificate. Cause: The two materials were entered separately, and no field-level comparison was performed by batch number.
  • Symptom: The certificate number on the education certificate is inconsistent with what was filled in on the registration form, and the supplementary review batch still uses the old version. Cause: The version was not synchronized, and the materials were not rechecked after being updated.
  • Symptom: After startup, the logs continuously report connection timeouts, and retrieval reports a vector database error. Cause: The connection variables do not match the actual instances, or the log database and main database are mixed without distinction.

How to verify the setup

Function acceptance: Connect once to the main business database, log database, cache, and vector database item by item, and check the connection results in the startup logs; check that the values of MONGODB_URI, REDIS_URL, and PG_URL are consistent with the deployment instructions, and the output is whether the connection is available.

Business test: Check once item by item according to the handover sheet, see which item is missing from the record, and check whether the fields, dates, and signatures of the registration form, education certificate, and work experience certificate are complete.

  • Check the values of MONGODB_URI and REDIS_URL in the deployment environment, review the service startup result and connection logs, and confirm that the main business database and cache are connectable.
  • Check the name, dates, quantities, and signature receipts of the registration form, education certificate, and work experience certificate item by item according to the handover sheet, register inconsistent items, and hand them over to the next shift.
