PSEB Class 11 Data Handling Practice

Data Handling is an important Class 11 Computer Science topic that introduces the basic ideas of data, information, databases, database management systems, data models, relational database structure, keys, and SQL commands.

Questions from this topic may ask students to distinguish data and information, identify the need for databases, compare file systems with database systems, recognise data models, understand relation, tuple, attribute, domain, degree, cardinality, and identify different types of keys used in relational databases.

Use this 20-question practice test before broader Class 11 Computer Science revision. After completing the test, review every explanation carefully and repeat the test after revising weak areas such as DBMS concepts, relational model, database keys, and basic SQL statements.

What to Review for Data Handling

Focus on database concepts, relational model, keys, and SQL basics.

Data and Database Basics

Review data, information, database, need of database, traditional file system, database system, DBMS, and advantages of using a database.

Relational Model

Practice relation, table, row, column, tuple, attribute, domain, degree, cardinality, and the structure of relational databases.

Keys and SQL

Revise candidate key, primary key, alternate key, foreign key, SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and basic SQL conditions.

Key Data Handling Concepts to Remember

Before repeating the test, make sure you can separate general database concepts from relational database terms. Many questions become easier when you can identify whether the question is about data, DBMS, tables, rows, columns, keys, or SQL.

Common Mistakes in Data Handling Questions

Data Handling questions often use similar terms, so small confusion can lead to wrong answers. When checking your result, see whether one of these common mistakes affected your answer:

  • Confusing data with information
  • Confusing database with DBMS
  • Thinking a database is only one table
  • Confusing file system with database system
  • Forgetting that DBMS helps manage databases
  • Confusing hierarchical model with relational model
  • Confusing relation with relationship
  • Calling a row an attribute
  • Calling a column a tuple
  • Confusing degree with cardinality
  • Forgetting that degree means number of attributes
  • Forgetting that cardinality means number of tuples
  • Confusing candidate key with primary key
  • Thinking every candidate key must be selected as primary key
  • Confusing alternate key with foreign key
  • Forgetting that a primary key uniquely identifies a record
  • Forgetting that a foreign key links two tables
  • Using SQL commands without understanding their purpose
  • Confusing SELECT with INSERT
  • Confusing UPDATE with DELETE

Data Handling Practice FAQ

Common questions about this PSEB Class 11 Computer Science Data Handling practice test.

Yes. The Data Handling practice test is free to use and does not require registration, payment, or a subscription.

The test contains 20 multiple-choice questions with four answer options, instant result checking, and detailed explanations.

Review data, information, database, DBMS, traditional file system, database system, data models, relational model, relation, attribute, tuple, domain, degree, cardinality, keys, and SQL basics.

A database is an organised collection of related data that can be stored, managed, searched, and updated efficiently.

DBMS stands for Database Management System. It is software used to create, store, manage, update, and retrieve data from a database.

In a relational database, a relation is a table that stores data in rows and columns.

A primary key is an attribute or group of attributes that uniquely identifies each record in a table.

A foreign key is an attribute in one table that refers to the primary key of another table. It is used to create a link between tables.
