File Processing System (FPS)

In earlier days, data was stored manually, using pen and paper but after computer was discovered, the same task could be done by using files. A computer File is a resource which uniquely records data, in a storage device in a computer. There are various formats in which data can be stored. e.g. Text files can be stored in .txt format while pictures can be stored in .png format etc.

In case of computer files, data about data (metadata) can be stored in different lines, separated by spaces, commas or tab to resemble tables. Each file is placed in relevant folders for the ease of access. This can be understood from the screenshot of Notepad below. For a school named GeeksforGeeks, having classes 1 to 5, the data can be stored in the file system in the following way.

Note –
Here, the school GeeksforGeeks has several classes, depicted through folders (Geeks of class 1, Geeks of class 2 etc.). The folders have files which carry the details of students (All Geeks.txt). The details are stored in tabular fashion, using spaces.

File Processing System :
In Computer Science, File Processing System (FPS) is a way of storing, retrieving and manipulating data which is present in various files.

Files are used to store various documents. All files are grouped based on their categories. The file names are very related to each other and arranged properly to easily access the files. In file processing system, if one needs to insert, delete, modify, store or update data, one must know the entire hierarchy of the files.

Advantages of File Processing System :

  • Cost friendly –
    There is a very minimal to no set up and usage fee for File Processing System. (In most cases, free tools are inbuilt in computers.)
  • Easy to use –
    File systems require very basic learning and understanding, hence, can be easily used.
  • High scalability –
    One can very easily switch from smaller to larger files as per his needs.

Disadvantages of File Processing System :

  • Slow access time –
    Direct access of files is very difficult and one needs to know the entire hierarchy of folders to get to a specific file. This involves a lot of time.
  • Presence of redundant data –
    The same data can be present in two or more files which takes up more disc space.
  • Difficulty in recovery of corrupt data –
    Recovery or backup of lost and corrupt data is nearly impossible in case of File Processing System.

Note –
Database Management System (DBMS) is used to eliminate the disadvantages of the FPS.
