Database Connections and Operations for School Exam Question Setting and Grading: Coordinate Operations and Application Handover

School Exams: review databases for operational handover. Compare the source records, required inputs and downstream results before handing the task over.

What this category's data looks like

This page addresses the scenario of exam question setting and grading in primary and secondary schools. Materials include the question-setting two-way specification table, exam papers, and scoring rubrics. When these materials enter the deployment, operations, and application handover function, each plays a different role: the two-way specification table is used to check knowledge points and question type distribution, exam papers are used to check question numbers and scores, and scoring rubrics are used to check answers and scoring points. Sources are school question-setting groups and academic affairs departments, and the update cadence advances by exam batch. Field characteristics center on names, quantities, dates, and signatures, which must be compared item by item during handover. On the deployment side, attention is paid to the connection status of the main business database, log database, cache, and vector database, ensuring consistency among version, connection, and task records.

Configuration and implementation checks

This step is handled by the connection configuration of the deployment environment (server side), not by the capability execution of model nodes, and outputs whether the connection is available (service startup result and connection logs). "Handover-ready deployment status and operation records" are then completed by deployment handover and subsequent business processing.

Three common errors

  • Symptom: The names and quantities of the same record do not match between the specification table and the exam paper. Cause: The two materials were updated separately and were not checked item by item according to the handover form.
  • Symptom: The scoring rubric version and the exam paper version are not synchronized, and signatures or receipts are missing. Cause: Versions and signature fields were not checked during handover, and missing items were not recorded.
  • Symptom: After startup, the logs continuously report connection timeouts, and retrieval reports vector database errors. Cause: Connection variables do not match the actual database addresses, or the log database and the main database are mixed up.

How to verify the setup

This function's acceptance: 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 are reachable.

Business test: perform one item-by-item check according to the handover form, see which item is missing from the records, and compare the names, quantities, dates, and signatures of the question-setting two-way specification table, exam papers, and scoring rubrics.

  • In the deployment environment, verify that the connection variable values for the main business database, log database, cache, and vector database match the database addresses, and record the connection results in the startup logs.
  • According to the handover form, verify item by item the names, quantities, dates, and signatures of the question-setting two-way specification table, exam papers, and scoring rubrics; record missing items and hand over to the next shift.
