Subdirectories help organize files within a system, while searching helps locate specific files or information within those directories.
What is the difference between flat file and DBMS?
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.
What is the difference between a file processing system and a database system?
A file processing system manages data using individual files, without any inherent structure for organizing or querying data. A database system uses a structured approach to store, retrieve, and manage data in a centralized repository, providing features like data consistency, concurrency control, and query capabilities through a database management system (DBMS).
What is the difference between database and file system?
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.
