The traditional file processing system is the computerized manual filing system. It is when a computer system stores permanent records.
you are helpful to all students in the whole world..thanks.Godbless you always.
File processing system is inconsistent and disintegrared.It is difficult to access and may be present on different platforms which would not allow to integrate data
File based approach can be attributed to two factors: 1. the definition of the data is embedded in the application programs, rather than being stored separately and independently. 2. there is no control over the access and manipulation of data beyond that imposed by the application programs. To become more effective, a new approach was required. What emerged were the database and the DBMS (Database management system).
Before the intruduction of this database concept many people used Manual Processing and File based systems.But there are some limitations. Manual Processing-Time consuming Does not support large volumes of data File Based System-Data Inconsistency Duplication of data Security problems And to overcome the limitations of these processing this Database processing was intruduced
is the way a file is design using a pascal language

Prior to the use of DBMS Traditional file processing system were in use . These were the system that are used as database that time. These system do not supports the query.

Relational model is better than traditional file processing system as it maintains data integrity ad security. Also Data in relational model is very easily accessible.

FIle processing systems was an early attempt to computerize the manual filing processing system that we are all familiar with. A file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. File systems may use a storage device such as hard disk or CD-ROM and involve maintaining the physical location of files.
Enforcing Security Constraints in file processing system is very difficult as the application programs are added to the system in an ad-hoc manner.
Some limitation of file processing include:1. Data redundancy and inconsistency2. Difficulty in accessing data3. challenges with data security4. Often, time consuming and tedious
Traditional file processing system lacks from DBMS in many ways . Major Disadvantage of FPS are it do not maintains data security and integrity efficiently.

Two of the drawbacks of a traditional file system are that, at the limits, data cannot be found easily (you need to remember the pathname of the file) or quickly (the access time depends on where the data is in the file).
Traditional file processing systems include manual systems and also computer based file systems that were linked to particular application programs. This is the type of file processing that you used with your 3GL programming. They share a number of characteristics.
