data abstractions 数据抽象

Computer Science An Overview _J. Glenn Brookshear _11th Edition

In this chapter we investigate how data arrangements other than the cell-by-cell organization provided by a computer’s main memory can be simulated a subject known as data structures. The goal is to allow the data’s user to access collections of data as abstract tools rather than force the user to think in terms of the computer’s main memory organization. Our study will show how the desire to construct such abstract tools leads to the concept of objects andobject-oriented programming.

本章将要研究的是如何对数据组织形式进行模拟，这门学科称为数据结构。它不同于由计算机内存所提过的以一个个单元来组织数据的方式。
其目标是让数据的使用者将数据集视为一种抽象工具来访问，而不是从计算机内存中的数据组织的角度去考虑问题。
