procedural abstraction

基本解释

Procedural abstraction, abstract data types, and, most recently, objects and components are all examples of such abstractions.
过程抽象、抽象数据类型、以及目前比较常用的“对象”和“组件”都属于这样的抽象机制。
Procedural Abstraction aims at replacing the machine-dependent objects of a procedure with representations, which are machine-independent.
过程抽象技术是用机器无关的表达方式对过程中与机器相关的内容进行抽象。
Because of the higher level of abstraction it provides, SQL, unlike procedural languages, lets programmers focus on what data they need, not how to retrieve it.
由于 SQL 与过程化语言不同，它提供了更高的抽象级别，因此它可以让程序员把精力集中到他们需要什么样的数据，而不是如何检索数据。
