Database Concepts Class 12 Important Questions
1. What is data?
Answer – Data is a collection of raw facts which have not been processed to reveal useful
information.
2. What is Database?
Answer – A database is an organized collection of structured information, or data, typically
stored electronically in a computer system. A database is usually controlled by a database
management system.
3. What are the different properties of Database?
Answer – The different properties of Database are –
1) A database is a representation of some aspect of the real world also called miniworld.
Whenever there are changes in this miniworld they are also reflected in the database.
2) It is designed, built and populated with data for specific purposes.
3) It can be of any size and complexity.
4) It can be maintained manually or it may be computerized.
4. Why is a database required?
Answer – Large amounts of data may be kept in one location, which makes databases a
suitable choice for data access. The data can be accessed and changed simultaneously by
several individuals. You can quickly and easily find the information you need in databases
since they can be searched and sorted.
5. What are the different advantages of Database?
Answer – Advantages of database are –
1. Reduction in Redundancy: All the data is stored at one place. There is no repetition of the
same data. This also reduces the cost of storing data on hard disks or other memory
devices.
2. Improved Consistency: The chances of data inconsistencies in a database are also
reduced as there is a single copy of data that is accessed or updated by all the users.
3. Improved Availability: Same information is made available to different users. This helps
sharing of information by various users of the database.
4. Improved Security: By making use of passwords and controlling users’ database access
rights, the DBA can provide security to the database.
5. User Friendly: Using a DBMS, it becomes very easy to access, modify and delete data.
6. What is a Database Management System?
Answer – A database management system is a group of applications that let users build,
administer, and use databases. It permits the development of a data repository that may be
created once and then accessible by various users in accordance with their needs. As a
result, all application programmes have access to a single data source.
7. What are the various operations performed by Database?
Answer
– The
various
operation
of
database
are
–
1. Defining the Database: It involves specifying the data type of data that will be stored in
the database and also any constraints on that data.
2. Populating the Database: It involves storing the data on some storage medium that is
controlled by DBMS.
3. Manipulating the Database: It involves modifying the database, retrieving data or
querying the database, generating reports from the database etc.
4. Sharing the Database: Allow multiple users to access the database at the same time.
5. Protecting the Database: It enables protection of the database from software/ hardware
failures and unauthorized access.
6. Maintaining the Database: It is easy to adapt to the changing requirements
8 What are the different characteristics of Database?
Answer – The different characteristics of database are –
a. Self-describing Nature of a Database System – The database management system
(DBMS) also includes a description of the data that it stores. Metadata refers to this
description of the data. A database catalog or data dictionary is where meta-data is kept. It
includes the data’s structure as well as the limitations placed on the data.
b. Insulation Between Programs and Data – Programs that access this data don’t need to
be changed because the description of the data is stored separately in the database
management system (DBMS) and any changes to the data’s structure are made in the
catalog. The term “Program-Data Independence” refers to this quality.
c. Sharing of Data – Multiple users can access the database at once in a multi user scenario.
Therefore, a DBMS must have concurrency control software to provide concurrent access
to the database’s data without encountering any consistency issues.
9. What are the different types of users of DBMS?
Answer – The different types of DBMS users are –
1. End Users – Users who use the database for querying, modifying and generating reports
as per their needs.
2. Database Administrator (DBA) – The DBA is responsible for authoring access, monitoring
its use, providing technical support, acquiring software and hardware resources.
3. Application Programmers – Application programmes write application programs to
interact with the database.
4. System Analyst – A system analyst plays a major role in the database design and all the
technical, economic and feasibility aspects.
10. What are the limitations of using DBMS?
Answer – Limitations of DBMS are –
a. High Cost – The cost of implementing a DBMS system is very high and a very time
consuming process.
b. Security and Recovery Overheads – Databases protect the data from unauthorized
access from the users.
11. What is a relational Database?
Answer – A collection of data elements with pre-established relationships between them
make up a relational database. These things are arranged in a series of tables with rows and
columns. To store data about the things that will be represented in the database, tables are
utilized.
12. What do you mean by domain constraint?
Answer – Columns with user-defined domain constraints make it easier for users to enter
values that relate to the data type. Additionally, it notifies the user that the column is not
properly filled in if it receives a faulty input.
13. What is entity integrity constraint?
Answer – This constraint specifies that the primary key of a relation cannot have null value.
The reason behind this constraint is that we know the primary key contains no duplicates.
14. What is the referential integrity constraint?
Answer – Foreign key constraints or referential integrity constraints. A logical rule about
the values in one or more columns in one or more tables is known as a foreign key
constraint, also known as a referential constraint or a referential integrity constraint.
15. How many SQL statements are used? Define them.
Answer – SQL statements are basically divided into two categories, DDL & DML.
a. Data Definition Language – Commands from the Data Definition Language (DDL) are
used to specify the structure holding the data. These commands are automatically
committed, which means that any database changes made by DDL commands are
permanently recorded.
b. Data Manipulation Language – The database’s data can be changed using Data
Manipulation Language (DML) commands. These instructions can be rolled back and are
not automatically committed.
16. Give an example of DDL & DML commands?
Answer
Data Definition Language (DDL) commands:
 CREATE table
 ALTER table
 DROP table
Data Manipulation Language (DML) commands:
 INSERT table
 UPDATE table
 DELETE
–

computer’s main memory is volatile, i.e., it is lost when we switch off the computer.
f. Storage – Huge amounts of data and information can be stored in a computer for future
retrieval. The human memory is limited and fades away with time, which is not true for a
computer.
2. What are the different memories in the computer system?
Answer – There are two different type of memory in computer system –
a. Primary Memory
b. Secondary memory
Primary Memory – Data stored in Primary Memory is directly accessible by the CPU. The
inputs received in the above steps are stored in the computer memory, called random
access memory (RAM). This storage is relatively fast and expensive as compared to the
secondary storage.
Secondary Memory – The memory which is external to the computer system forms the
secondary storage, for example, the magnetic tapes, compact disks, pen drives are all
examples of the secondary storage. These are not directly connected to the CPU.
