Here are four significant differences between a file processing system and a DBMS:
Data redundancy: In a file processing system, data is often stored in multiple files, resulting in data redundancy. This redundancy can lead to data inconsistencies and make it difficult to maintain data integrity. In contrast, a DBMS uses a single integrated database, which minimizes data redundancy and ensures data consistency.
Data dependence: In a file processing system, data is often dependent on the specific application programs that use it. This makes it difficult to modify the data structure or add new data without changing the application programs. In contrast, a DBMS separates the data from the application programs, allowing for greater flexibility and easier modification of the data structure.
Data isolation: In a file processing system, data is often stored in separate files, making it difficult to access and update data across multiple applications. This can lead to data inconsistency and make it difficult to integrate data from different sources. In contrast, a DBMS provides a single, centralized database that can be accessed by multiple applications, ensuring data consistency and facilitating data integration.
Security: File processing systems provide limited security mechanisms to protect the data from unauthorized access or modification. In contrast, a DBMS provides robust security features, such as access control, authentication, and encryption, to protect the data from unauthorized access or modification.
The major disadvantages of a file processing system include:
Data redundancy: As mentioned earlier, data redundancy can lead to inconsistencies and errors in the data.
Data dependence: Changing the data structure in a file processing system often requires modifying the application programs that use the data, which can be time-consuming and error-prone.
Limited data sharing: Data in a file processing system is often isolated, making it difficult to share data across multiple applications.
Data inconsistency: Data in a file processing system can become inconsistent if it is updated in one file but not in another.
Poor security: File processing systems often lack robust security mechanisms, making it difficult to protect the data from unauthorized access or modification.
