Decoupling the data from the system applications is a major difference between the centralized database approach and the applications approach and is known as:
A) data independence
B) data manipulation
C) data redundancy
D) query language

Quizplus · Accepted Answer

Data independence refers to the ability to modify the data schema without affecting the applications that use the data. This is a key feature of the applications approach, where the data is decoupled from the system applications. In contrast, in the centralized database approach, the data schema is tightly coupled with the system applications. Data manipulation (B) refers to the ability to manipulate data using operations such as insert, update, and delete. Data redundancy (C) refers to the duplication of data, which can lead to inconsistencies and inefficiencies. Query language (D) refers to a language used to retrieve specific data from a database. Although query language is related to data independence, it is not as directly related as data independence is to the decoupling of data from applications.
