Disadvantage in File Processing System?
Disadvantages of File Processing Systems include:
1. Program-Data Dependence. File descriptions are stored within each application program that accesses a given file.
2. Duplication of Data.Applications are developed independently in file processing systemsleading to unplanned duplicate files. Duplication is wasteful as itrequires additional storage space and changes in one file must be mademanually in all files. This also results in loss of data integrity. Itis also possible that the same data item may have different names indifferent files, or the same name may be used for different data itemsin different files.
3. Limited data sharing. Eachapplication has its own private files with little opportunity to sharedata outside their own applications. A requested report may requiredata from several incompatible files in separate systems.
4. Lengthy Development Times.There is little opportunity to leverage previous development efforts.Each new application requires the developer to start from scratch bydesigning new file formats and descriptions
5. Excessive Program Maintenance. The preceding factors create a heavy program maintenance load.
6. Integrity Problem. The problem of integrity is the problem of ensuring that the data in the database is accentuate.
7. Inconsistance data
8. Security
. The Problem of security in file processing is Non Programmer canretrieve modify, delete and insert the data in data base. But this isnot possible in DBMS
