Difference between File Oriented System and DBMS
What is File Processing System?
At an earlier age, the computer system was used to store business records and produce different information. They were usually faster and more accurate than similar manual systems. These systems stored groups of documents in a separate file and so they were called file processing system.
In a typical file processing system, each administration has its files, created especially for those functions. The department itself works with the data processing staff, sets policies or standards for the format and maintenance of its data.
Advantages of the file-oriented system
Following are the advantages of the file-oriented system are
It is feasible to take quicker and programmed back-up of the database saved in files of computer-based frameworks.
Computer frameworks offer functionalities to fill this purpose. It is also feasible to create a specific application software for this purpose.
It is feasible to save document compactly.
Computer-based frameworks offer enhanced data retrieval approach to retrieve records saved in files quickly and efficiently way.
It is simple to edit any records stored in computers in the structure of files. Specific application functions or editing applications can be utilized for this purpose.
Information stored in files of computer-based frameworks can be shared among multiple users at a similar time.
Disadvantages of the File-Oriented System
Following are the disadvantages of the file-oriented system are
Since all the documents are independent of each other. Some fields are stored in more than one file.
In the file processing system, data is not consistent. If a data element is to be transferred, then all the documents, including that data required to be updated. The problem lies in the risk that all the data might not be updated, causing inconsistency.
Poor Data Integrity
Integrity means the unification of several files into one file. A group of data has integrity. If data is logically consistent, that is, duplicate data items agree with one another.
If it is needed to extract data from two different files, it will be required to determine which parts of each of the files are required, then how the files are related to one another.
Atomicity means that an operation in any transaction should happen in its entirety or not at all. Since the information needed to roll back a transaction may not be readily available in a file processing system, ensuring the atomicity of transactions will be difficult.
Concurrency Control Problem
It is challenging to build in concurrency control features at the application program level.
Poor Data Security
Data is stored in different files causing the security of problems.
What is DBMS?
DBMS stands for Database Management System, and it facilitates to create and control databases, which can be collections of records. Furthermore, DBMS stores data in tables. Here, first, the user has to create the structure to save the data. Then the data storage take place according to that architecture.
File Oriented System vs. Database System
|File Oriented System||Database System|
|File System is a global, easy-to-use system to store general files which require less protection and constraints.||A database management system is utilized when security constraints are high.|
|The file system provides the elements of the data representation and storage of records.||DBMS gives an abstract record of facts that hides the elements.|
|In the file system, data redundancy is large.||In DBMS, Data redundancy is low.|
|Concurrent access to the record in the file structure has many issues like reading the document while other structure of locking, deleting some data, updating some data.||DBMS looks after concurrent access using some structure of locking.|
|The file system doesn’t support a crash recovery mechanism.
E.g., While we are entering some record into the file, if the system crashes, then the content of the information is lost.
|DBMS has a crash recovery mechanism. DBMS protects the customer from the effects of system failures.|
|Security is small in the File Management System.||Security is huge in the Database Management System.|
|A file Management System stores unstructured data as separate record files/entities.||Database Management System stores structured records that have well-defined constraints and interrelation.|
|A file management system is suitable for small organizations or a single customer.||DBMS is feasible for huge organizations to support multiple customers.|
