7.5.1 representing data with structural patterns

If we discuss the program based on the data structure, rather than on the object, we can say that the structure pattern is a common and effective way to describe the design data structure, and the design pattern is more specific, which shows how to implement these structures in object-oriented language using objects. In this chapter, we see methods for representing data in a functional way. The first approach, we use a simple list of records, it is easy to write in any one language, and the second presentation method (using a differential union) makes more sense. Let's take a look at the first pattern, the compound pattern (composite pattern).
