• Members table (member registration and profiles)
• Bookings table (pool time slot reservations)
• Trainers table (staff management)
• Payments table (fee collection and tracking)
• Lockers table (locker assignment)
• Memberships table (membership plans and renewals)
• Pool_Schedule table (availability management)
