A file-based data management system also called a file system is a type of software that allows users to access and organize small groups of data. It is usually integrated into a computer's operating system and is responsible for storing and retrieving files from a storage medium, such as a hard disk or flash drive.

As in the university database, name, class, roll no is the same information of a student that is stored in different files. So, in a file-based system, data duplication is there. Data Dependence If the format of a certain record was changed, then we must update the record in each file containing that format to avoid confusion. Hence, it is

For example, a simple database named Sales has one primary file that contains all data and objects and a log file that contains the transaction log information. A more complex database named Orders can be created that includes one primary file and five secondary files. The data and objects within the database spread across all six files, and the four log files contain the transaction log

Learn what a file based system is, how it works, and its advantages and disadvantages. A file based system is a simple and inexpensive way to organize and maintain data files, but it has limitations in size, security, and complexity.

The system that reads or manipulates the data cannot make easy connections between the data represented. File-based systems usually don't have any type of user or data concurrency features either. Flat file databases are usually only practical for systems with small read or write requirements. For example, many operating systems use flat-files

A file-based system must manage, or prevent, concurrency by the application programs. Typically, in a file-based system, when an application opens a file, that file is locked. This means that no one else has access to the file at the same time. In database systems, concurrency is managed thus allowing multiple users access to the same record.

The stability of the SQLite database file format and the fact that the file format is cross-platform combine to make SQLite database files an excellent choice as an Application File Format. The US Library Of Congress acknowledges this by listing SQLite as a recommended storage format for long-term preservation of digital content.

In file based database, data was maintained in a flat-file. Though files have many advantages, there are several limitations. One of the major advantages is that the file based system has various access methods, e.g., sequential, indexed and random. It requires extensive programming language in third generation language such as COBOL,BASIC.

Database Approach File Based Approach DBMS or Database Management System is a software application. It is used for accessing, creating, and managing databases. A file system is a software that manages and organizes the files in a storage medium. It controls how data is stored and retrieved.

SQLite is a self-contained, file-based, and fully open-source RDBMS known for its portability, reliability, and strong performance even in low-memory environments. In contrast, SQLite allows any process that accesses the database to read and write to the database disk file directly. This simplifies SQLite's setup process, since it
