CREATE INDEX idx_pet_archived ON tbl_pet(archived);
-- Similar changes for all other tables

Enhanced Display Methods

// Professional table display with complete information
public void displayPetsTable(List<Pet> pets)

// Detailed individual pet information
public void displayPetDetails(int petId)

// Archive management methods
public boolean archivePet(int petId)
public boolean restorePet(int petId)
public List<Pet> getArchivedPets()

Specialized Update Methods

// Targeted update methods for better performance
public boolean updatePetBasicInfo(int petId, String name, String description, int age)
public boolean updatePetHealthInfo(int petId, String healthStatus, String vaccinationStatus)
public boolean updatePetAdoptionStatus(int petId, String adoptionStatus)
public int batchUpdateAdoptionStatus(List<Integer> petIds, String adoptionStatus)
