Frequently Asked Questions
Q1: What is a database management system?
A1: An inter related data collection that helps in successful retrieval, insertion and deletion of data from database and organizes the complete data into tables, views, reports etc is known as database. A software that is used to manage all these data in database is known as Database management system. Data definition, data updation, data retrieval, user administration allows users to manage the database system.
Q2: What was the necessity to shift from File system to Database management system?
A2: Files in Hard disk is used to manage the data in File system. The one who uses file system is allowed to create, modify, edit, delete and update the files according to the requirement. Issues with this particular system are,
- Inconsistency of data
- Difficulty in accessing the data
- Redundancy in data
- Unauthorized access
- No backup or recovery of the data
- No concurrent access
Because of these reasons Database management system is required and hence the shift.
Q3: What is DDL and DML?
A3: Data Definition Language (DDL) is a database schemas and description about how data should be stored
Data Manipulation Language (DML) focuses on data manipulation.
