Disadvantages of a typical proceeding system

 

The main disadvantages of a typical proceeding system are as under:

 

§         The data redundancy and inconsistency: Since the files are created for each application differently, the files are likely to have different formats and data designs as they are created by different designers and programmers over a period of time.   Hence, the same data record may be present in more than one file, the creation, updation, and deletion of which is managed by different programmes. Over a period of time, a situation arises when the data is redundant and inconsistent, due to the changes not being incorporated simultaneously, in all the applications and in all the files.

 

§         Difficulty in access to the data: In conventional system design, the file structure is consistent to the specific information needs. If the information needs change, gaining access to the data present in different files to satisfy the revised need, requires writing the necessary application programmes every time. This is difficult and very time consuming at critical times.

 

§         Concurrent access anomalies: In a dedicated file system application, the concurrent access is provided to improve the response of processing; however, the file systems are incapable of supervising and coordinating the changes arising out of the concurrent access to the record.

 

§         Security problems: The file systems have a limitation of controlling the access to the record causing insecurity with respect to the information. Since the application programmes are written time and again it is difficult to enforce a discipline on the security constraints across all the applications.

 

§         Integrity of the data: In a file system it is difficult to maintain integrity of the data across the applications. The integrity rules are added when the programmes are written. If any change in the rules occur, it is very difficult to ensure that it is affected across the files in all the applications.
