# Data clumps > 코드 악취 중 하나. 같이 몰려다니는 데이터가 있는데 의미 있는 단위로 묶이지 않은 상황. [코드 악취](https://wiki.g15e.com/pages/Code%20smell.txt) 중 하나. 같이 몰려다니는 데이터가 있는데 의미 있는 단위로 묶이지 않은 상황. > Data items tend to be like children: They enjoy hanging around together. Often, you’ll see the same three or four data items together in lots of places: as fields in a couple of classes, as parameters in many method signatures. Bunches of data that hang around together really ought to find a home together. --Chapter 3, [Refactoring: Improving the design of existing code](https://wiki.g15e.com/pages/Refactoring%20-%20Improving%20the%20design%20of%20existing%20code.txt) ## 관련 리팩토링 - - -
