In a DBMS, the user requests for data by submitting queries written in a structured query language (SQL). These queries are then processed by the DBMS to locate and retrieve the requested data from the database tables. For example, a user can request all records of employees who work in a specific department by writing a SQL query that specifies the department's name and selects the relevant data fields. The DBMS then executes this query, retrieves the matching data from the database, and presents it to the user.
The full form of DBMS is Database Management System.
DBMS (Database Management Systems) are important in an information-based society because they provide a structured way to store, manage, and retrieve data efficiently. They help in organizing and maintaining large volumes of data, ensuring data consistency and integrity, and enabling quick access to pertinent information. DBMS also support data sharing and collaboration among users, leading to enhanced decision-making processes and overall business performance.
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.
