Disadvantage of Computer File-based Processing System
Although a computer file-based processing system has many advantages over manual record keeping system, but it has some limitations. The basic disadvantages (or limitations) of computer file-based processing system are described below.
- Data Redundancy
- To update a specific data/record, the same data must be updated in all files, otherwise different file may have different information about a specific item.
- A valuable storage space is wasted.
- Data Inconsistency
- Data Isolation
- Data Atomicity
- Data Dependence
The physical structure of data files and records are defined in the application program code. It is difficult to change the structure of data files or records. If you want to change the structure of data file (or format of file), then you have to modify the application program.
- Program Maintenance
- Data Sharing
- Data Security
- Incompatible File Format
