Walkthrough

The PR introduces database schema documentation and a PostgreSQL migration script for a recruitment management system. It includes ERD diagrams, schema specifications, a comprehensive SQL migration with tables, foreign keys, constraints and indexes, and a prompt document defining roles for database experts.

Changes

Cohort / File(s) Summary
ERD and Schema Documentation
backend/prisma/ERD.md, backend/prisma/ERD_update.md
Added Mermaid ER diagrams and detailed documentation of the candidate and recruitment management schemas, defining entities (Candidate, Education, WorkExperience, Resume, Company, Employee, Position, Interview, etc.), relationships, attributes, and design considerations.
Database Migration
backend/prisma/migration_erd_update.sql
Added PostgreSQL migration script with table creation for Company, Employee, Position, InterviewFlow, InterviewType, InterviewStep, Application, and Interview entities; includes foreign key constraints, CHECK constraints for validation, multiple indexes for query optimization, transaction management, and commented rollback instructions.
Prompt Documentation
prompts/promtps-wca.md
Added comprehensive Spanish-language prompt defining roles for database and migration experts, specifying requirements for generating ERD diagrams and PostgreSQL migration scripts from Prisma schemas, including constraints, indexing, data preservation, and safe migration practices.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • backend/prisma/migration_erd_update.sql requires careful verification of:
    • Foreign key relationships and cascade behavior across interdependent tables
    • CHECK constraints for data validation correctness
    • Index definitions and their alignment with query patterns
    • Transaction integrity and rollback sequence
  • backend/prisma/ERD_update.md and prompts/promtps-wca.md involve detailed documentation review for accuracy and completeness
  • Cross-reference the SQL migration against ERD documentation to ensure schema consistency

Poem

🐰 A schema fair with tables neat,
ER diagrams, SQLs complete,
Constraints cascade, indexes gleam,
A migration script—a DBA's dream! ✨
With prompts to guide, the path is clear,
A recruitment system takes shape here! 🎯

🧹 Nitpick comments (2)
backend/prisma/ERD.md (1)

1-126: Documentation is comprehensive; address Spanish grammar and punctuation.

The documentation effectively explains the candidate management schema, relationships, and design rationale. However, numerous Spanish grammar and punctuation issues throughout the file detract from clarity. Most notably, the static analysis flags missing periods/commas in bullet-point lists (e.g., lines 68–72, 77–82, 86–94, 97–102), and a few capitalization/spelling variations.

These are minor issues for a documentation file, but consider applying a grammar pass (or using a Spanish grammar checker) to improve consistency before publication, especially if this is external-facing documentation.

prompts/promtps-wca.md (1)

1-13: First prompt section is incomplete; expand task description.

Lines 3–13 define a role and task for understanding the schema and generating an ERD, but the task description is brief and lacks specificity. Consider elaborating on:

  • Expected output format and level of detail
  • How to handle optional/nullable fields
  • Reference to specific schema files (e.g., ERD_update.md)
  • Validation criteria for the generated ERD

Compare this to the detailed requirements in the migration prompt (lines 17–47), which provides comprehensive guidance.

🔇 Additional comments (4)
backend/prisma/migration_erd_update.sql (4)

1-10: Migration script is well-structured with proper transactional safety and documentation.

The script follows PostgreSQL and migration best practices: transactional integrity (BEGIN/COMMIT), idempotent operations (IF NOT EXISTS), comprehensive CHECK constraints, proper indexing, and documented rollback procedures. The structured approach (core tables → level-1 dependents → level-2 dependents → level-3 dependents) correctly respects foreign key dependencies.


85-92: Verify ON DELETE RESTRICT policy for POSITION/InterviewFlow relationship.

Line 87–88 defines ON DELETE RESTRICT for the POSITIONInterviewFlow foreign key. This prevents deletion of an interview flow if any position references it. Confirm this aligns with your business logic—if a position can exist without an interview flow, or flows should be soft-deleted, consider ON DELETE SET NULL or ON DELETE CASCADE instead.

For comparison, INTERVIEW_STEPINTERVIEW_FLOW (line 105) uses ON DELETE CASCADE, which will cascade-delete interview steps when a flow is deleted.


117-131: Verify CASCADE delete behavior for APPLICATION → POSITION and → CANDIDATE.

Lines 126–129 specify that deleting a position or candidate will cascade-delete all related applications. This is a significant data-loss scenario—if a position is marked inactive (rather than deleted), consider using soft-delete patterns or ON DELETE SET NULL to preserve application history.

Similarly, line 151 cascades application deletion to all interviews. Verify this is the intended behavior, as it permanently removes interview records and feedback when an application is deleted.


145-157: Score range constraint is inclusive of 0–100; clarify intent.

Line 157 defines: CONSTRAINT chk_interview_score CHECK (score IS NULL OR (score >= 0 AND score <= 100)). This allows scores 0–100, with NULL for pending/no-show interviews. Confirm this matches your grading scale—if 0 is invalid (e.g., scoring is 1–100), adjust the constraint.

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Verify ERD diagram consistency with migration script and existing schema.

The Mermaid diagram is well-structured and defines all recruitment entities and relationships. However, the CANDIDATE entity appears in the diagram but is not created in migration_erd_update.sql—it's expected to be an existing table per the migration comments. Verify that:

  1. The CANDIDATE entity and its attributes match the existing schema (typically defined in the candidate-related tables noted in ERD.md)
  2. All foreign key relationships in lines 78–87 are correctly implemented in the migration script
  3. Cardinality matches the migration's ON DELETE and ON UPDATE rules

🏁 Script executed:

#!/bin/bash
# Verify ERD diagram entities match migration script table definitions

echo "=== Entities in ERD diagram ==="
grep -oP '^\s+\K\w+(?=\s*\{)' backend/prisma/ERD_update.md | sort | uniq

echo ""
echo "=== Tables created in migration script ==="
grep -oP 'CREATE TABLE IF NOT EXISTS "\K[^"]+' backend/prisma/migration_erd_update.sql | sort | uniq

echo ""
echo "=== CANDIDATE references in migration ==="
rg -C2 'REFERENCES.*Candidate'

Length of output: 863



---

🏁 Script executed:

```shell
#!/bin/bash
# Search for Candidate table definition across migration files

echo "=== Searching for CREATE TABLE.*Candidate ==="
rg -i 'create table.*candidate' backend/prisma/ || echo "No matches found"

echo ""
echo "=== Listing all migration files ==="
ls -la backend/prisma/migrations/ 2>/dev/null || ls -la backend/prisma/*.sql | head -20

echo ""
echo "=== Checking if Candidate is defined in migration_erd_update.sql ==="
grep -i 'create table.*candidate' backend/prisma/migration_erd_update.sql || echo "Candidate CREATE TABLE not found in migration_erd_update.sql"

Length of output: 407


Migration script is missing Candidate table definition—foreign key constraint references non-existent table.

The ERD diagram correctly includes the CANDIDATE entity, but migration_erd_update.sql does not create the corresponding table. However, the Application table's foreign key constraint references "Candidate"(id), which will cause the migration to fail with a "referenced table does not exist" error.

The migration script must include a CREATE TABLE statement for the Candidate table with columns matching the ERD diagram (id, firstName, lastName, email, phone, address) before the Application table is created.

🤖 Prompt for AI Agents
In backend/prisma/migration_erd_update.sql (around the Application CREATE TABLE
and its preceding statements), the migration omits creating the Candidate table
while Application declares a foreign key to "Candidate"(id); add a CREATE TABLE
"Candidate" statement before creating Application with columns id (primary key,
integer/serial), firstName (varchar), lastName (varchar), email (varchar), phone
(varchar), address (text) to match the ERD, ensure the table name/casing matches
the FK reference, and update the down/rollback section (if present) to drop
Candidate in the correct order.

⚠️ Potential issue | 🟡 Minor

Fix critical typos in prompt filename and line 9.

Two critical issues in this file:

  1. Filename: promtps-wca.md appears to be a typo and should be prompts-wca.md. Verify if this is intentional.
  2. Line 9: Contains two errors:
    • "pronfundidad" should be "profundidad"
    • "entiende" should be capitalized to "Entiende" (starts a sentence)
    • "mermaid" should be capitalized to "Mermaid"

Also note line 15 has a double space: "Prompt Migración" → "Prompt Migración".

Apply this diff to fix the typos:

🤖 Prompt for AI Agents
In prompts/promtps-wca.md around lines 1-13 (and note the double space at line
15), rename the file to prompts-wca.md to fix the filename typo, correct line 9
by changing "pronfundidad" to "profundidad", capitalize "entiende" to
"Entiende", and capitalize "mermaid" to "Mermaid"; additionally remove the extra
space at line 15 so "Prompt  Migración" becomes "Prompt Migración".
