📋 What Gets Documented

✅ Metadata Extracted

Object Type	Information Included
Tables	Name, columns, data types, constraints, indexes, row counts
Views	Name, columns, dependencies (no SQL definition)
Routines	Name, type, parameters, return type, signature (no body)
Sequences	Min/max values, increment, current value
Triggers	Name, timing, event, target table (no trigger code)
Synonyms	Name, target object, owner
Indexes	Name, columns, type, uniqueness
Columns	Name, data type, nullable, default, constraints

❌ Security Exclusions

The following are NEVER extracted to prevent IP leakage:

• ❌ Stored procedure/function bodies
• ❌ Trigger implementation code
• ❌ View SQL definitions
• ❌ Any executable scripts or logic

⚙️ Configuration

Sample Configuration

database:
  type: "oracle"
  host: "localhost"
  port: 1521
  database: "ORCL"
  username: "system"
  password: "oracle"

output:
  format: "markdown"
  output_dir: "./output"
  include_toc: true
  language: "en"

extract:
  include_tables: true
  include_views: true
  include_routines: true
  include_sequences: true
  include_triggers: true
  include_synonyms: true
  exclude_system: true

See config.example.yaml for all options.

🧪 Validation

Ensure compliance with security and quality rules:

go run tools/validate_phase1.go

Expected Output:

✅ PASS Rule: NO SOURCE CODE FIELDS (Security)
✅ PASS Rule: COMMENT FIELDS ON ALL STRUCTS (Rich Metadata)
✅ PASS Rule: FULL OBJECT COVERAGE
✅ PASS Rule: VIPER COMPATIBILITY (mapstructure tags)

✅ ALL CHECKS PASSED - Phase 1 Complete!

🛡️ Security Guarantees

1. No Source Code Extraction: Procedures, functions, triggers, and views are documented by signature/metadata only
2. Safe for External Sharing: Generated documentation contains no proprietary logic
3. Compliance-Ready: Suitable for security audits and public wikis
4. Configurable Filtering: Exclude sensitive schemas or tables
