Database Connections and Operations for Exam Organization and Misconduct Handling: Track Progress and Check Statistics

Exam Administration: 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 exam organization and violation handling scenarios, with materials drawn from three categories: exam manuals, examination room record sheets, and violation fact records. The exam manual provides subjects, times, examination room arrangements, and responsibility assignments; the examination room record sheet carries the actual attendance number, absences, abnormal situations, and invigilator signatures; the violation fact record registers candidate information, behavior descriptions, evidence lists, and handling receipts. The three types of materials are updated by session, summarized into the progress table within the week, and at month-end form the statistical scope statement. Field characteristics are concentrated in four categories: dates, names, quantities, and signatures: dates must be consistent with the session, names must be consistent with the roster, quantities must be consistent with the actual attendance total, and signatures and receipts must be complete. When the materials enter the progress record and statistical verification function, the exam manual provides the scope baseline, the examination room record sheet provides process records, and the violation fact record provides exception details; together the three support matching the record count with the statistical count and writing the scope into the table header.

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 "progress table and statistical scope statement" is then completed by deployment handover and subsequent business processing.

ObjectCheckVerification action
Primary business database connection variablePoints to the primary business database actually in use and can connect, corresponding to the fields, dates, and signature verification dimensions of the exam manual, examination room record sheet, and violation fact recordIn the deployment environment, check that the variable value is consistent with the database address, and connect once to the primary business database item by item
Log database connection variableConfigured separately, or left empty per instructions to reuse the primary database; the log write location is verified separately from the primary business dataCheck whether the variable is set, verify the database to which logs are written, and connect once to the log database item by item
Cache connection variableThe cache instance can connect, used for streaming recovery mirroring and memory watermark detectionUse a client to connect once to the cache instance, verify the return, and connect once to the cache item by item
Vector database connection variableConsistent with the vector database actually in use; when retrieval reports a vector database error, this can be used to locate itCheck the selected vector database and address against the deployment instructions, and connect once to the vector database item by item

Three common errors

  • Symptom: The name, quantity, and date of the same record do not match between the examination room record sheet and the violation fact record. Cause: The two materials are registered separately, and fields and totals are not unified according to the exam manual scope.
  • Symptom: The progress table and the statistical scope statement versions are not synchronized, and the totals are inconsistent with the table header scope. Cause: The update cadence differs, the old scope is still in use, and no version check has been done.
  • Symptom: The violation fact record lacks a signature or receipt, and is included or omitted during statistics. Cause: Exceptions are not clearly written, and signatures and receipts are not completed before summarization.

How to verify the setup

Acceptance of this function: 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; connection addresses are configured by environment variables, and the primary business database, log database, cache, and vector database can point to different instances respectively; when the log database is not configured separately, it reuses the primary database.

Business test: use one week of records to verify the totals and see whether the scope and exceptions are clearly written; check the tokens of the referenced text, record the array length separately, the reference count is the array length, quoteMaxToken is the reference content budget, and the two are not compared for equality.

  • In the deployment environment, check that the value of MONGODB_URI is consistent with the primary business database address, and check whether the log database variable is set or left empty per instructions to reuse the primary database.
  • Use a client to connect once to REDIS_URL and verify the return, check the vector database variable and address against the deployment instructions, and confirm that the selected vector database is consistent with the one actually in use.
