Symbolic data representation , how pattern matching is used to pack / unpack data , how functions are combined to form programs etc 抽象数据表示，模式匹配来打包/解包数据，函数如何组合成为程序等。
The abstract data types of haskell in many ways provide a more straightforward route to enforcing validity than do oop attribute restrictions 与oop属性限制相比， haskell的抽象数据类型在很多方面提供更简单的方法来实施有效性。
He lacks not only technical know - how , but also an understanding of the abstract , of how to interpret even the simplest technical drawings 他不仅缺乏技术知识，而且也不能理解抽象数据，不知道如何解释，即使是最简单的技术图表。
So far a class , an abstract data type , and a set of possible values together with operations , i . e . , a data type , are pretty much the same 到现在为止，一个抽象数据类型，一些可能的值及其的一些操作，例如一个的数据类型已经更加相似于一个类了。
An abstract data type is just a contiguous chunk of data associated with an address point to it , cast it about , pick it apart , and move on swiftly 抽象数据类型只是与地址相关联的连续数据块指向它，对它进行强制转换，对它进行解析，然后快速向前推进。
The theory of abstract data types will provide the key to this problem , by allowing programs to access data by external properties rather than physical implementation 抽象数据类型的理论将会提供这个问题的答案,既允许程序用外部特性而非物理实现来存取数据
With an abstract data type we cleanly separate the programming tasks of implementation and usage : we are well on our way to decompose a large system into smaller modules 通过抽象数据类型我们干净地把实现和使用两种编程任务分开：我们在把一个大系统分成小模块的道路上顺利前行。
Model uses the soap encoding rules to represent the abstract soap data model and relies on the vendors soap library to provide the concrete implementation of the abstract soap data model 模型使用soap编码规则来表述抽象soap数据模型，并依赖厂商的soap库来提供抽象数据模型的具体实现。
Technically , oop is just about abstract data typing , inheritance , and polymorphism , but other issues can be at least as important . this section will cover these issues 从技术上来说，面向对象仅仅是指抽象数据类型、继承和多态，但是还有一些问题也行挺重要的，这一节将对这些问题进行讨论。
Xquery is designed from the ground up to support aggregations that span multiple documents , but its basic method is to define a very rigorous data model and semantics of the abstract data being queried Xquery完全是为了支持跨越多个文档的聚合而设计的，但它的基本方法是为查询的抽象数据定义非常严格的数据模型和语义。
