FILE ORIENTED APPROACH:

 The earliest business computer systems were used to process business records and produce information. They were generally faster and more accurate than equivalent manual systems. These systems stored groups of records in separate files, and so they were called file processing systems. 

• .File system is a collection of data. Any management with the file system, user has to write the procedures 
• File system gives the details of the data representation and Storage of data. 
• In File system storing and retrieving of data cannot be done efficiently. 
•  Concurrent access to the data in the file system has many problems like a Reading the file while other deleting some information, updating some information 
• .File system doesn’t provide crash recovery mechanism. Eg. While we are entering some data into the file if System crashes then content of the file is lost.
•   Protecting a file under file system is very difficult.

 The typical file-oriented system is supported by a conventional operating system. Permanent records are stored in various files and a number of different application programs are written to extract records from and add records to the appropriate files.
