Database Connections and Operations for School Teacher Training Credits: Coordinate Operations and Application Handover

Teacher Credits: 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 is intended for the scenario of credit management for primary and secondary school teacher training. The materials include training notices, credit recognition forms, and participant lists. A training notice provides the training topic, start and end dates, and organizing unit, and serves as the prerequisite basis for credit recognition; a credit recognition form records the teacher's name, ID document number, training project, recognized credits, and recognition date, and requires the signature of the person in charge; a participant list lists the names of participating teachers, their units, participation dates, and sign-in receipts. When these three types of materials enter the deployment, operations, and application handover function, their roles differ: training notices and participant lists are used to verify the training facts and the scope of personnel, while credit recognition forms are used to verify the recognition results and signature status. The update rhythm advances by training batch, with centralized entry after each batch of training ends, and the field characteristics are concentrated in dates, names, quantities, and signature receipts. During handover, the three types of materials must be checked together with the deployment status and operation records under the same batch, to avoid the same record having inconsistent names, quantities, or dates across two materials.

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, 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.

ObjectCheckVerification action
Primary business database connection variablePoints to the primary business database actually in use and can connect, and the fields and dates of training notices, credit recognition forms, and participant lists can be queried in that databaseIn the deployment environment, check that the variable value matches the database address, and connect once to the primary business database item by item
Log database connection variableConfigured separately, or left blank according to the instructions to reuse the primary database, and the database to which logs are written can be distinguished from the business databaseCheck whether the variable is set, verify the database to which logs are written, and confirm that business data and logs are not mixed in the same place
Cache connection variableThe cache instance can connect, and the parameters related to streaming recovery mirroring take effect at their default valuesConnect once with a client, verify the return, and check the connection result in the startup logs
Vector database connection variableMatches the vector database actually in use, and when retrieval reports a vector database error, the selected vector database and address can be locatedCheck 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 same teacher's name or participation date does not match between the credit recognition form and the participant list. Cause: The two materials were entered at different times, and the fields and dates were not checked under the same batch.
  • Symptom: The training name in the training notice is inconsistent with the project name in the credit recognition form. Cause: The versions were not synchronized, and after the notice was updated, the recognition form still used the old name.
  • Symptom: The credit recognition form lacks the signature of the person in charge, or the participant list lacks sign-in receipts. Cause: During handover, only quantities were checked, not signatures and receipts, and the materials were not closed-loop.

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, check the connection results in the startup logs, and verify that the three connection addresses MONGODB_URI, PG_URL, and REDIS_URL match the deployment instructions.

Business test: check once item by item according to the handover form, see which record is missing, and focus on checking the fields, dates, and signatures of training notices, credit recognition forms, and participant lists.

  • In the deployment environment, check that the variable value matches the database address, and connect once to the primary business database, log database, cache, and vector database item by item, recording the connection results in the startup logs.
  • Check the fields, dates, and signatures of training notices, credit recognition forms, and participant lists item by item according to the handover form, and confirm that versions are synchronized and that there are no missing signatures or receipts.
