Which of the following term is best defined by the statement: "CASE tools and the target applications are isolated from physical storage so they are not affected when the hardware configuration is changed." ?
Correct answer: B. Data independence
- A. Non-redundant data storage
- B. Data independence
- C. Data dependence
- D. Ad Hhoc data queries and reports
Explanation
Data independence separates CASE tools and applications from the details of physical storage, so hardware or storage changes do not require changes to them. Data dependence means the opposite, where software is tied to storage details.
