Technical Details

Database Export Format

The export includes all tables:

• Users
• Characters (with all relations: Eigenschaften, Lps, Aps, etc.)
• Skills (SkFertigkeiten, SkWaffenfertigkeiten, SkZauber)
• Equipment (EqAusruestungen, EqWaffen, EqContainers)
• GSMaster data (Skills, WeaponSkills, Spells, Equipment, Weapons, etc.)
• Learning data (Sources, CharacterClasses, SkillCategories, etc.)
• Audit log entries

Import Behavior

• Uses Save() for upsert logic (updates existing records, creates new ones)
• Maintains referential integrity
• Wrapped in transaction (all-or-nothing)

Testing

All functionality is fully tested with TDD approach:

go test -v ./transfer/
