procedural abstraction

基本解释

Procedural abstraction, abstract data types, and, most recently, objects and components are all examples of such abstractions.
過程抽象、抽象數據類型、以及目前比較常用的“對象”和“組件”都屬於這樣的抽象機制。
Procedural Abstraction aims at replacing the machine-dependent objects of a procedure with representations, which are machine-independent.
過程抽象技術是用機器無關的表達方式對過程中與機器相關的內容進行抽象。
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.
由於 SQL 與過程化語言不同，它提供了更高的抽象級別，因此它可以讓程序員把精力集中到他們需要什麽樣的數據，而不是如何檢索數據。
