File System Critique
Structural and Data Dependence
- Structural Dependence
A change in any file’s structure requires the modification of all programs using that file.
- Data Dependence
A change in any file’s data characteristics requires changes in all data access programs.
- Significance of data dependence is the difference between the data logical format and the data physical format.
- Data dependence makes file systems extremely cumbersome from a programming and data management point of view.
