What is data independence, and why is it lacking in file systems?

What will be an ideal response?


Answer: Data independence exists when you can change the data storage characteristics without impeding the program's ability to access the data.

Any program that accesses a file system's file must tell the computer not only what to do, but how to do it. Consequently, each program must contain lines that specify the opening of a specific type of file, its record specification, and its field definitions. Data dependence makes the file system extremely cumbersome from the point of view of a programmer and database manager.
