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).
A file processing system and a database management system (DBMS) are two different ways of managing data in a computer system. A file processing system is a traditional method of storing data in which data is stored in separate files, and programs are written to read, write and manipulate these files. A DBMS, on the other hand, is a software system designed to manage databases that can store and retrieve data in an organized and efficient manner.
The main difference between a file processing system and a DBMS is how data is stored and accessed. In a file processing system, data is stored in individual files created and maintained by different programs. These programs are often developed separately and may need help accessing data stored in other files. This can result in data duplication, inconsistency, and inefficiency. Furthermore, file processing systems typically lack mechanisms to enforce data integrity and security, which can result in data loss, corruption, or unauthorized access.
In contrast, a DBMS stores data in a centralized database that can be accessed by multiple programs simultaneously. The DBMS provides all programs with a consistent and unified view of the data, eliminating data redundancy and inconsistency. Additionally, a DBMS provides built-in mechanisms for ensuring data integrity, security, and concurrency control, which prevent data corruption and unauthorized access.
Another key difference between a file processing system and a DBMS is flexibility and scalability. A file processing system is typically designed for a specific application or task and may not easily accommodate new requirements or changes. In contrast, a DBMS is designed to be flexible and scalable, allowing users to add, modify, or delete data and to customize the system to meet changing business needs.
Finally, a DBMS provides a range of advanced features and functionality not available in file processing systems. These include support for complex data types, such as multimedia and spatial data, and advanced query and reporting capabilities. A DBMS also provides features such as data mining, data warehousing, and online transaction processing, which are critical for managing large and complex databases.
In summary, a file processing system and a DBMS are two different ways of managing data in a computer system. While file processing systems are simple and easy to implement, they need more flexibility, scalability, and advanced functionality than DBMSs. DBMSs provide a centralized, secure, and efficient way of storing and retrieving data, offering a range of advanced features critical for managing large and complex databases.
DBMS overcomes all the disadvantage of traditional FPS. The main difference between FPS and DBMS is that FPS do not support data sharing, data security and non redundancy.
A traditional file processing system do not support to ask query . A database management system allows you to ask query . Also DBMS maintain data security and consistency.
There are many differences between a traditional FPS and a DBMS. The main difference is the security and integrity that is maintained in DBMS but not in FPS.

Active file: An active file is where you use a file quite frequently. Inactive file: A file that you use but not as frequently. Dead file: A dead file is where you don't use the file at all and is stored in your archives

A project file is a file which contains information about your program. This could include source code, resources (images, sounds, etc.), and configuration files. A data file is a file which is actually used by your program to persist data between sessions.

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
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.
In DBMS Multiple user can access file at a time. but in flat file system only one user can access file at a time

1) In a traditional file processing system the work of IT was very hectic while this is not so in DBMS.2) In DBMS redundancy of data is tried to reduced while this was not so in FPS. 3) DBMS maintains data integrity but FPS do not.
storing and retrieving data is faster,flexibility over file processing,real time transactio processing,trac records useful in auditing and control.
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.

A database is a structured collection of data organized for efficient retrieval, storage, and manipulation, while a file system is a method used by operating systems to store, organize, and access files on a computer. Databases provide features like data integrity, relationships, and query capabilities, whereas file systems primarily focus on storing and managing individual files.

In file processing system a permanent system file is created for every new object. Application softwares are used to manipulate these files. SO characteristics (Some of them became its drawbacks) of file processing system are:- 1)Data redundancy and inconsistency 2)Difficulty in accessing data 3)Data isolation ie. data is in different formats and files. In database system these issues where addressed, by data abstraction. In DBMS, data is stored using 3 levels of abstraction 1)Physical Level : How data is stored 2)Conceptual level : What data is stored, relationship between data 3)View Level : What is visible to different users.
