Database Connections and Operations for College Admissions and Application Placement: Coordinate Operations and Application Handover

College Admissions: 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 includes enrollment plans, filing rules, and admission rosters. The sources are provincial admissions and examination institutions and university admissions offices. They are updated by batch and round, and the fields include institution code, major group, planned number, filing cutoff line, admission status, date, and signature field. When enrollment plans enter the deployment environment, they serve as the verification baseline for the primary business database. Filing rules participate as versioned configuration in consistency checks for connections and task records. Admission rosters serve as the item-by-item verification object for the handover form. For the same record, the name, quantity, and date in the three must be consistent with the two sets of materials, and both version synchronization and signed receipts are indispensable. When the materials enter the database and operations functions, they each assume the roles of connection object, task record, and handover evidence, and the deployment status and operation records must form a traceable chain around these three types of materials.

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 it 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. The connection addresses of the primary business database, log database, cache, and vector database are configured separately through environment variables. If the log database is not configured separately, it reuses the primary database.

ObjectCheckVerification action
Enrollment planInstitution code, major group, planned number, and date are consistent in the two sets of materials, the version is synchronized, and signatures are completeIn the deployment environment, verify that the variable value is consistent with the database address, and compare the plan fields, date, and signature item by item
Filing rulesFiling conditions, round, and date are consistent in the two sets of materials; if the version is not synchronized, it is deemed inconsistentCheck the selected vector database and address against the deployment instructions, and inspect the rule version and task records
Admission rosterCandidate number, admission status, quantity, and date are consistent in the two sets of materials; if a signature or receipt is missing, it does not passUse the client to connect to the cache once and verify the return; verify the roster records item by item according to the handover form
Deployment status and operation recordsVersion, connection, and task records are consistent; if any record is missing, handover is not possibleVerify the connection results and startup logs of the primary business database, log database, cache, and vector database

Three common errors

  • Symptom: after startup, the logs continuously report connection timeouts. Cause: the primary business database or cache connection variable is inconsistent with the actual instance address, and the deployment environment did not verify against the variable value.
  • Symptom: the name, quantity, and date of the same record do not match in the two sets of materials. Cause: the versions of the enrollment plan and admission roster were not synchronized, and the handover form was not verified item by item.
  • Symptom: retrieval reports a vector database error. Cause: the vector database connection variable is inconsistent with the vector database actually used, or the log database and primary database are shared, causing confusion about the write location.

How to verify the setup

This function's acceptance: connect once each to the primary business database, log database, cache, and vector database item by item, verify the connection results in the startup logs, and confirm that MONGODB_URI, PG_URL, and REDIS_URL point to the actual instances and can be connected.

Business test: verify once item by item according to the handover form and see which record is missing; the fields, dates, and signatures of the enrollment plan, filing rules, and admission roster must be consistent with the two sets of materials.

  • In the deployment environment, verify that the value of the primary business database connection variable is consistent with the database address, check whether the log database variable is set, and verify the database to which logs are written.
  • Use the client to connect to the cache once and verify the return, check the selected vector database and address against the deployment instructions, and inspect whether the task records and version are synchronized.
