What is a structural dependence?
A file system exhibits structural dependence, which means that access to a file is dependent on its structure. For example, adding a customer date-of-birth field to the CUSTOMER, Given this change, none of the previous programs will work with the new CUSTOMER file structure. Therefore, all of the file system programs must be modified to conform to the new file structure. In short, because the file system application programs are affected by change in the file structure, they exhibit structural dependence. Conversely, structural independence exists when it is possible to make changes in the file structure without affecting the application program’s ability to access the data.
