-# Usage
-```python
-db = DB()
-
-# 문자열 저장 및 조회
-db['hello'] = 'world'
-print(db['hello'])  # 출력: world (str 타입)
-
-# 숫자 저장 및 조회
-db['number'] = 42
-print(db['number'])  # 출력: 42 (int 타입)
-
-# 바이너리 데이터 저장 및 조회
-db['binary'] = b'binary data'
-print(db['binary'])  # 출력: b'binary data' (bytes 타입)
-
-# 복잡한 객체 저장
-complex_obj = {'name': 'John', 'age': 30, 'city': 'New York'}
-db['complex'] = complex_obj
-loaded_obj = db['complex']
-print(loaded_obj)  # 출력: {'name': 'John', 'age': 30, 'city': 'New York'} (dict 타입)
-
-db['test_key'] = 'test_value'
-
-print(db.exists('test_key'))  # True
-print(db.exists('non_existent_key'))  # False
-```
