List any two significant differences between a file processing system and a DBMS. File Processing System vs. DBMS
Data Independence - Data independence is the capacity to modify the schema at one stage of a database system without having to modify the schema at the further level. In file processing systems the data and applications are commonly interdependent, but DBMS gives the feature of data independence.
Data Redundancy - Data redundancy means needless duplication of data. In file processing systems there is redundancy of data, but in DBMS we can decrease data redundancy through means of normalization procedure without affecting the original data. If we do so in file processing system, it becomes too complex.
