procedural abstraction

基本解釋

Procedural abstraction, abstract data types, and, most recently, objects and components are all examples of such abstractions.
過程抽象、抽象數(shù)據(jù)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(jī)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(shù)是用機(jī)器無關(guān)的表達(dá)方式對過程中與機(jī)器相關(guān)的內(nèi)容進(jìn)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麼樣的數(shù)據(jù)，而不是如何檢索數(shù)據(jù)。
