In previously days, data to be stored manually, making use of pen and file but after computer was discovered, the exact same task could be done by making use of files. A computer system File is a resource which uniquely documents data, in a storage an equipment in a computer. There are various styles in i m sorry data have the right to be stored. E.g. Text files can it is in stored in .txt layout while pictures have the right to be save in .png format etc.In case of computer system files, data about data (metadata) deserve to be save on computer in various lines, be separated by spaces, commas or tab come resemble tables. Each paper is put in pertinent folders because that the lull of access. This can be understood from the screenshot of Notepad below. For a school named, having classes 1 to 5, the data can be stored in the paper system in the adhering to way.

You are watching: One disadvantage of file processing systems is:

Attention reader! Don’t stop learning now. Get hold of all the necessary CS Theory principles for SDE interviews with the CS concept Course in ~ a student-friendly price and also become market ready.
Note –Here, the school has several classes, depicted through folders (Geeks of class 1, Geeks of course 2 etc.). The folders have records which bring the details of student (All Geeks.txt). The details space stored in tabular fashion, using spaces.File Processing device :In computer Science, paper Processing device (FPS) is a means of storing, retrieving and manipulating data which is existing in miscellaneous files.Files are used to store assorted documents. All documents are grouped based on their categories. The file names are very related to each other and also arranged correctly to easily access the files. In paper processing system, if one requirements to insert, delete, modify, save or upgrade data, one must know the whole hierarchy of the files.Advantages of record Processing system :Cost friendly –There is a an extremely minimal come no set up and usage fee for file Processing System. (In many cases, complimentary tools room inbuilt in computers.)Easy to usage –File systems need very an easy learning and understanding, hence, can be easily used.High scalability –One can an extremely easily move from smaller to larger papers as per his needs.Disadvantages of document Processing mechanism :Slow accessibility time –Direct accessibility of files is very daunting and one needs to know the whole hierarchy of folders to obtain to a specific file. This entails a lot of time.Presence of redundancy data –The exact same data deserve to be existing in 2 or an ext files which takes up much more disc space.Inconsistent Data –Due to data redundancy, exact same data stored at various places could not complement to each other.Data Integrity problems –The data existing in the database have to be consistent and correct. To attain this, the data should must satisfy specific constraints.Difficulty in recovery of corrupt data –Recovery or backup of lost and corrupt data is practically impossible in situation of record Processing System.Lack that Atomicity –Operations perform in the database should be atomic i.e. One of two people the operation takes location as a totality or does not take place at all.Problem in Concurrent access –When a number of users operates ~ above a common data in database at the very same time then anomalies arise, as result of lack the concurrency control.
