What is File Processing System?

 What is File Processing System? 

Ans. The FPS allows permanent records in various files and it needs different application programs to extract records from and add records to the appropriate files. Each time when need arises system programmers write these application programs to meet the needs so, that system acquires more application programs, more files which will be time consuming always. It creates complexity, reduces efficiency of the system. FPS has a number of disadvantages, which are given below:

 1. Data redundancy.

 2. Inconsistency.

 3. Data Isolation.

 4. Accessing problem .

5. Security .

6. Concurrency.

 7. Integrity .

8. Database 

As shown in the figure, in a FPS, different programs in the same application may be interacting with different private data files. There is no system enforcing any standardised control on the organisation and structure of these data files..
